Function
The biosynthesis of lipid-linked oligosaccharides is highly conserved among eukaryotes and is catalyzed by 14 glycosyltransferases in an ordered stepwise manner. The Alg1 mannosyltransferase I (MT I) catalyzes the first mannosylation step in this process.{{cite web | title = Entrez Gene: ALG1 asparagine-linked glycosylation 1 homolog (S. cerevisiae, beta-1,4-mannosyltransferase)| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=56052}} Clinically, the deficiency of ALG1 in humans results in ALG1-CDG, a congenital disorder of glycosylation.{{cite web|url=https://www.omim.org/entry/608540|title=# 608540 CONGENITAL DISORDER OF GLYCOSYLATION, TYPE Ik; CDG1K | publisher=Johns Hopkins University | access-date = 2019-05-01}}
