  Figure 2. 34 exons of USP32.
Description USP32 gene is located on a prominent gene amplification region, 17q23, in breast cancers (Bärlund et al., 1997; Erson et al., 2001) and has 34 exons (figure 2).
Transcription USP32 mRNA is 7026 bp long. Coding sequence of USP32 starts at the 287th bp and ends at the 5101st bp of the mRNA. Total length of USP32 coding sequence is 4815 bp.
Pseudogene No pseudogene has been reported for USP32.


Note Three independent studies reported USP32 to be phosphorylated at the 1173rd tyrosine and 1372nd serine residues (Dephoure et al., 2008; Rigbolt et al., 2011; Mayya et al., 2009).
Description USP32 (ubiquitin specific protease 32 - accession number: NT_010783 and mRNA accession number: NM_032582) encodes for a protein consisting of 1604 amino acids and the resulting protein's predicted molecular weight is approximately 182 kDa. The N-terminal region contains calcium binding domain with EF-hand and DUSP domains.
The EF-hand calcium binding domains, consisting of a helix (E), a loop and a second helix (F) motif, are generally found in calcium binding proteins.
DUSP domain is common among ubiquitin specific proteases. The function of this domain in USP32 remains unclear but is predicted be functional in protein-protein interactions. In addition, USP32 harbors Cys, His and Asp triad which is common in USP subfamily of DUBs (figure 3). Recently, active deubiquitination function of USP32 has been established (Akhavantabasi et al., 2010).
  Figure 3. Domains of USP32.
Expression Overexpressed transcript was detected in malignant breast ephitelium (Grigoriadis et al., 2006). Another study showed overexpression of USP32 in 50% (9 of 18) of breast cancer cell lines and 22% (9 of 41) of primary breast tumors compared to mammary epithelial cells (Akhavantabasi et al., 2010).
Localisation Golgi (Akhavantabasi et al., 2010).
Function USP32 is an active deubiquitinating enzyme (Akhavantabasi et al., 2010).
Homology C-terminal of USP32 shows 97% nucleotide homology with USP6 (ubiquitin specific protease 6 (Tre-2 oncogene)) (Paulding et al., 2003) (figure 4).


Note In the Parkinson disease, CNVs in USP32 gene were suggested. However, these variations in USP32 were not confirmed with Multiplex ligation-dependent probe amplification (MLPA) and real time PCR (Pankratz et al., 2011).

Implicated in

Entity Breast cancer
Note USP32 is located on 17q23 chromosomal region which is amplified in breast cancer (Sinclair et al., 2003; Haverty et al., 2008). Real-time PCR analysis in breast cancer cell lines determined that USP32 transcript is amplified more than two-fold in 50% of breast cancer cell lines and in 22% of (9 of 41) primary breast tumors compared to normal breast tissue samples. Moreover, silencing of USP32 leads to a decrease in the proliferation and migration properties of HeLa and MCF7 cells (Akhavantabasi et al., 2010).
In estrogen receptor (ER) positive tumors, USP32 may have a higher copy number than ER negative tumors (Zhang et al., 2009). Scafoglio et al. (2006) suggest USP32 to be an estrogen responsive gene.
Hybrid/Mutated Gene RT-PCR and transcriptome sequencing analysis determined USP32 to be one of the twelve expressed fusion genes in breast cancer cell line ZR-75-30. USP32 is found to be expressed with CCDC49 as a fusion transcript (Schulte et al., 2012).
