STT3B - STT3 oligosaccharyltransferase complex catalytic subunit B Gene

Homo sapiens

Also known as SIMP; CDG1X; STT3-B

Gene ID: 201595 | Gene type: protein coding

About STT3B

Cytogenetic location: 3p23 Genomic coordinates (GRCh38): 3:31,532,925-31,637,616 (from NCBI)

This gene has 7 transcripts (splice variants), 274 orthologues, 2 paralogues and is associated with 3 phenotypes. Ubiquitous expression in testis (RPKM 42.8), thyroid (RPKM 37.3) and 25 other tissues.

Summary

The protein encoded by this gene is a catalytic subunit of a protein complex that transfers oligosaccharides onto asparagine residues. Defects in this gene are a cause of congenital disorder of glycosylation Ix (CDG1X). [provided by RefSeq, Jun 2014]
