About ST3GAL3

Cytogenetic location: 1p34.1 Genomic coordinates (GRCh38): 1:43,707,536-43,931,159 (from NCBI)

This gene has 85 transcripts (splice variants), 254 orthologues, 14 paralogues and is associated with 5 phenotypes. Broad expression in testis (RPKM 4.7), fat (RPKM 2.9) and 25 other tissues.

Summary

The protein encoded by this gene is a type II membrane protein that catalyzes the transfer of sialic acid from CMP-sialic acid to galactose-containing substrates. The encoded protein is normally found in the Golgi apparatus but can be proteolytically processed to a soluble form. This protein is a member of Glycosyltransferase family 29. Mutations in this gene have been associated with a form of autosomal recessive nonsymdromic cognitive disability as well as infantile epileptic encephalopathy. Multiple transcript variants encoding several different isoforms have been found for this gene. [provided by RefSeq, Jul 2017]
