Abstract
This entry reviews the structure, function and clinical significance of YEATS4, a gene originally identified from an amplicon on 12p15 found in a glioblastoma cell line and originally named glioma-amplified sequence (GAS41). The gene is amplified in several other cancers and translocations or rearrangements of chromosome 12 with breakpoints in YEATS4 are noted in such cancers as glioblastoma, lung cancer and soft tissue sarcomas. Several frameshift and one nonsense mutations have also been detected in cancer. As the YEATS4 protein is involved in chromatin modeling, transcriptional regulation and mitotic regulation, such aberrations are likely to deregulate cellular mechanisms involved in the normal control of cellular proliferation and cell death.

Function
Further evidence for a function of YEATS4 in transcription has come from direct interactions with transcription factor TFAP2A (AP-2) (Ding et al., 2006), and the C-terminal region of the myc family members MYCN and MYC (Piccinni et al., 2011), identified by affinity capture techniques such as yeast two-hybrid analysis, GST-pull down and coimmunoprecipitation. The β-catenin gene (CTNNB1) is regulated by binding of YEATS4 to its promoter, either via these transcription factors, or in combination with the chromatin modeling complexes discussed above (Ji et al., 2017; Jixiang et al., 2017). Downstream targets of β-catenin such as CCND1 (Cyclin D1), CDK4, CDK6 and c-Myc, and the apoptotic proteins BCL2 and BAX also respond to overexpression and decreased expression of YEATS4 in gastric cancer and pancreatic cancer (Ji et al., 2017; Jixiang et al., 2017).
As noted above, the Tip60 and SCRAP complex play roles in double-stranded DNA repair. However, YEATS4 is involved in the regulation of DNA repair independent of these complexes. YEATS4 overexpression results in destabilization of TP53, with downregulation of YEATS4 leading to stabilization of p53 with concomitant upregulation of p53 target genes such as CDKN1A (p21), and induction of senescence and apoptosis (Llanos et al., 2006; Park et al., 2006; Pikor et al., 2013; Tao et al., 2015). Furthermore, overexpression of YEATS4 increases resistance of normal bronchial epithelial cells to the platinum drug cisplatin and p53- MDM2 interaction inhibitor, nutlin (Pikor et al., 2013). Mechanistically, YEATS4 acts with PP2Cβ to dephosphorylate ser-366 on p53, and can decrease cell death due to UV-induced DNA damage (Park et al., 2011). Thus, overexpression of YEATS4 may contribute to the cancers described below in part by overcoming the tumor suppressor properties of p53.
Additional functions of YEATS4 in nuclear architecture and regulation of mitotic spindle assembly were uncovered shortly after its discovery. Harborth et al., (2000) performed yeast two-hybrid analysis to identify proteins that bind to the C-terminus (amino acids 1048-2115) of NUMA1 (NuMA). Further mapping indicated that YEATS4 bound via its coiled coil domain to the C-terminal region of the coiled-coil rod domain of NuMA (amino acids 1048-1700). This interaction was confirmed independently by co-immunoprecipitation, Dot Overlay Assays, Surface Plasmon Resonance, and by a separate study (Munnia et al., 2001). Later studies showed that interaction between NuMA and YEATS4 was cell-cycle regulated with the interaction being low in G1 to S, increasing in S phase and being maximal at G2/M (Schmitt et al., 2012). NuMA is a nuclear matrix protein that relocalizes to and anchors microtubules to the spindle poles (reviewed in Haren et al., 2009). Manipulation of the expression of YEATS4 and NuMA via expression plasmids and siRNA results in an increased rate of spindle defects leading to multipolar spindles and misaligned chromosomes (Schmitt et al., 2012). Additional interactions of YEATS4 with CEP162 (Munnia et al., 2001), and TACC1 - TACC2 - TACC3 (Lauffart et al., 2002; Lauffart et al., 2003), proteins with known roles in centrosomal dynamics during mitosis (Gergley et al., 2000a,b; Leon et al., 2006), have also been identified. However, even these YEATS4-interacting proteins have been implicated in transcriptional regulation. For instance, during interphase NuMA binds to and acts as a transcriptional coregulator of p53 upon DNA-damage (Endo et al., 2013; Ohata et al., 2013); CEP162 associates with predominantly nuclear localized KAT14 lysine acetyltransferase (Gupta et al., 2015; Wang et al., 2008); and the TACC proteins bind to nuclear localized histone acetyltransferases (Gangisetty et al., 2004), nuclear hormone receptors (Vettaikkorumakankauv et al., 2008; Guyot et al., 2010; Hein et al., 2015; Huttlin et al., 2017) and other transcription factors (Sadek et al., 2000; Simpson et al., 2004); Bargo et al., 2010), and coregulate their transcriptional targets.
YEATS4 has been found in complexes with a further 108 proteins by high-throughput analysis via affinity purification-mass spectrometry (Li et al., 2015; Huttlin et al., 2015; Huttlin et al., 2017). Many of these interactions support the proposed functions of YEATS4 in the TIP60 and SCRAP complexes, transcriptional regulation, and mitotic regulation. For instance, additional transcription factors of relevance to cancer, such as FOS, Fox family members, and the myc partner MAX have been identified as YEATS4-binding factors (Li et al., 2015).

Implicated in

Four genomic rearrangements involving YEATS4 have been noted in glioblastoma. Frattini et al. (2013) performed RNA-sequencing of 161 primary GBM and 24 short-term glioma sphere cultures. These authors detected a single rearrangement t(12;12)(q14.1;q15), resulting in a fusion between YEATS4 and XRCC6BP1 (X-ray repair cross-complementation group 6 binding protein 1). XRCC6BP1 (AKA ATP23) is involved in double-stranded DNA break repair (Fischer et al., 2013) and, based on homology via its metalloprotease domain, is suggested to be important in the biosynthesis of mitochondrial ATPase (Zeng et al., 2007). The detected transcript indicates that the fusion protein contains the YEATS domain fused to the majority of the peptidase M76 domain of XRCC6BP1 (missing 20 amino acids at the N-terminus) (Fig. 6).


One rearrangement involving YEATS4 was detected in a study of 95 rectal adenocarcinomas by RNA-seq analysis and recorded in the TUMOR FUSION GENE DATA PORTAL. The rearrangement is identical to that observed in hepatocellular adenocarcinoma, fusing YEATS4 exon 6 to the final (noncoding exon) of CPSF6 (Fig. 11). Thus, the predicted fusion protein contains a truncated YEATS4 coding sequence contain the YEATS domain, but lacking the C-terminal coiled coil domain.
One case of a t(12;12)(q15;q15) fusing exon 6 of YEATS4 to exon 2 of the human lysozyme gene (LYZ) was identified from 414 cases in the Tumor Fusion Gene Data Portal. The resulting fusion protein contains the YEATS domain and the hydrolytic catalytic cleft of lysozyme. This rearrangement is identical to that detected in liver hepatocarcinoma cancer (see Fig. 10).


The TUMOR FUSION GENE DATA PORTAL (2017) reports one case of a t(12;12)(q15;q15) from 541 Lung adenocarcinomas, involving YEATS4 and SLC35E3. The rearrangement fuses YEATS4 (exon 4) to exon 4 of SLC35E3 resulting in part of the YEATS domain to 65 amino acids of the triose phosphate transporter domain (Fig. 12).

One case t(1;12)(q21.3;q15) fuses the exon 4 of KCNN3 (potassium calcium-activated channel subfamily N member 3)(based on transcript NM_002249) in-frame to exon 2 of YEATS4. The fusion protein would be 740 amino acids long and contain the calcium-activated SK potassium channel domain and part of the ion channel domain (pfam03530 and pfam07885) from KCNN3 and the YEATS4 YEATS domain and coiled coil domain (Fig. 13).
In a different tumor, another in-frame fusion occurs between exon 2 of MARCH9 on 12q14.1 and exon 2 of YEATS4 (Fig. 14). MARCH9 is a member of the MARCH family of membrane-bound E3 ubiquitin ligases. The fusion protein product is 380 amino acids long, containing the C4HC3 zinc-finger like RING domain and the YEATS4 YEATS domain and coiled coil domain.
The other three translocations observed fuse YEATS4 exon 7 out of frame 3-prime to its fusion partner, suggesting that these rearrangements produce a truncated protein lacking any YEATS4 components. One case of t(1;12)(q24.2;q15) fuses exon 16 of a coactivator of ligand-dependent nuclear receptors, DCAF6, to exon 7 of YEATS4 (Fig. 15). A truncated protein would contain the WD40 and cl26247 (DNA polymerase III, delta subunit) domains involved in transcriptional regulation, but miss the final 200 amino acids of the coactivator. A single t(12;12)(q21.1;q15) fuses exon 1 of the THAP domain containing, apoptosis associated protein 2 ( THAP2) out-of-frame to exon 7 of YEATS4. The "fusion protein would also be truncated, and only contain the first 24 amino acids of the THAP2 protein, and 5 amino acids encoded out of frame from exon 7 of YEATS4 (Fig. 16). The last case noted was an out of frame fusion between exon 10 of TMTC1 and exon 7 of YEATS4 t(12;12)(p11.22;q15). If the truncated 564 amino acid fusion protein is produced, it would lack the C-terminal tetratricopeptide repeats of TMTC1 (Fig. 17).
