Glycosyl hydrolase enzymes hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety. This gene encodes a member of glycosyl hydrolases family 31. This enzyme hydrolyses terminal, non-reducing 1,4-linked alpha-D-glucose residues and releases alpha-D-glucose. This is a key enzyme in glycogen metabolism and its gene localizes to a chromosomal region (15q15) that is associated with susceptibility to diabetes. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Aug 2014]

Protein Gene Interaction Pubs
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 The alpha-glucosidase inhibitor N-butyldeoxynojirimycin (NB-DNJ) inhibits HIV-1 entry and this inhibition correlates with impaired HIV-1 gp120 shedding and gp41 exposure and with changes in antibody recognition of gp120 PubMed
env Imino sugar N-butyldeoxynojirimycin (NB-DNJ) inhibits HIV envelope glycoprotein gp120 processing mediated by alpha glucosidase I PubMed
env Glucosidase inhibitors inhibit the syncytium formation between HIV-infected and CD4-expressing cells and interfere with HIV-1 infectivity, indicating processing of HIV-1 gp120 by glucosidase is important for virus replication PubMed
env HIV-1 gp120 is extremely heavily glycosylated (31-36 N-linked glycans per molecule) by glucosidase 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
env Inhibitors of alpha-glucosidase inhibit syncytium formation induced by the envelope glycoprotein of HIV-1 and reduce processing of the HIV-1 envelope precursor protein gp160 by glucosidase 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

NCBI Reference Sequences (RefSeq)

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.
