Summary
This gene encodes a glycosyl hydrolase that localizes to the Golgi and catalyzes the final hydrolytic step in the asparagine-linked oligosaccharide (N-glycan) maturation pathway. Mutations in the mouse homolog of this gene have been shown to cause a systemic autoimmune disease similar to human systemic lupus erythematosus. [provided by RefSeq, Dec 2013]

Envelope surface glycoprotein gp120 env Specific alterations of the N-linked carbohydrates on HIV-1 gp120 and gp41 by glucosidases and mannosidase inhibitors can enhance mannose-binding lectin (MBL)-mediated neutralization of virus by strengthening the interaction of HIV-1 with MBL PubMed
env HIV-1 gp120 N-linked oligosaccharides are processed by manosidase I and II in the Golgi complex PubMed
Envelope surface glycoprotein gp160, precursor env Oligosaccharide side-chains of HIV-1 gp160 are processed by glycosidase I and II, mannosidase I and II, acetylglucosaminyl transferase I and II, and fucosyl, galactosyl and sialyl transferases in both the endoplasmic reticulum and golgi apparatus PubMed
Envelope transmembrane glycoprotein gp41 env Mannose-containing, N-linked oligosaccharide side-chains of HIV-1 gp41 are involved in the initial stage of infection by HIV-1; glycosylation inhibitors block virus-cell and cell-cell fusion and release of the virions PubMed

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
