Homo sapiens

Also known as TMC; ITM1; STT3-A; CDG1WAD; CDG1WAR

Gene ID: 3703 | Gene type: protein coding

About STT3A

Cytogenetic location: 11q24.2 Genomic coordinates (GRCh38): 11:125,591,769-125,623,091 (from NCBI)

This gene has 17 transcripts (splice variants), 213 orthologues, 2 paralogues and is associated with 5 phenotypes. Ubiquitous expression in thyroid (RPKM 41.7), endometrium (RPKM 25.2) and 25 other tissues.

Summary

The protein encoded by this gene is a catalytic subunit of the N-oligosaccharyltransferase (OST) complex, which functions in the endoplasmic reticulum to transfer glycan chains to asparagine residues of target proteins. A separate complex containing a similar catalytic subunit with an overlapping function also exists. Multiple transcript variants encoding different isoforms have been found for this gene.
