Description The GLTSCR2 gene comprises 13 exons resulting in a transcript of 1567 bases. The start codon is in the 1st exon; the stop codon is in the 13th exon. Northern blot analysis shows a 1.5-kb transcript.
Transcription mRNA: ubiquitously
Pseudogene Not known


Description 478 amino acids. GLTSCR2 protein contains a putative PEST sequence (PEST score: +7.23, aa: 279-332) and a potential nuclear localization signal (aa: 378-386).
Localisation Nucleolus
Function GLTSCR2 protein binds to PTEN tumor suppressor and regulates its stability in cells. Recent reports show the implication of GLTSCR2 in cell proliferation and apoptosis.
Homology GLTSCR2 orthologs can be found in metazoans. In addition, GLTSCR2 protein shares homology with yeast Nop53p which is involved in ribosome biogenesis.


Note There are several synonymous and nonsynonymous SNPs reported for GLTSCR2 (S16R, Q169E, C325F, A383V, Q389R).

Implicated in

Entity Cancer
Note A number of groups have proven that the 19q13.32 locus where GLTSCR2 gene locates is frequently altered in glioma and neuroblastoma; however, a tumor suppressor gene(s) specifically encoded in this region has yet to be identified and the implication of GLTSCR2 gene in these tumors remains controversial. Recent studies show aberrations in GLTSCR2 expression in glioblastoma and neuroblastoma.
