Summaries for TUSC3 Gene

Entrez Gene Summary for TUSC3 Gene

  • This gene is a candidate tumor suppressor gene. It is located within a homozygously deleted region of a metastatic prostate cancer. The gene is expressed in most nonlymphoid human tissues including prostate, lung, liver, and colon. Expression was also detected in many epithelial tumor cell lines. Two transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for TUSC3 Gene

TUSC3 (Tumor Suppressor Candidate 3) is a Protein Coding gene. Diseases associated with TUSC3 include syndromic intellectual disability and autosomal recessive non-syndromic intellectual disability. Among its related pathways are Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein and Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein. GO annotations related to this gene include magnesium ion transmembrane transporter activity and dolichyl-diphosphooligosaccharide-protein glycotransferase activity. An important paralog of this gene is MAGT1.

UniProtKB/Swiss-Prot for TUSC3 Gene

  • Magnesium transporter (PubMed:19717468). May be involved in N-glycosylation through its association with N-oligosaccharyl transferase (PubMed:24685145).
