May be involved in N-glycosylation of APP (amyloid-beta precursor protein). Can modulate gamma-secretase cleavage of APP by enhancing endoprotelysis of PSEN1. {ECO:0000269|PubMed:21768116, ECO:0000305}. |OST3 OST6| |dolichyl-diphosphooligosaccharide-protein glycotransferase activity| |oligosaccharyltransferase complex| |protein N-linked glycosylation via asparagine| |peptidyl-asparagine modification| |protein N-linked glycosylation| |protein glycosylation| |macromolecule glycosylation| |glycosylation| |glycoprotein biosynthetic process| |glycoprotein metabolic process| |carbohydrate derivative biosynthetic process| |peptidyl-amino acid modification| |carbohydrate derivative metabolic process| |organonitrogen compound biosynthetic process| |cellular macromolecule biosynthetic process| |macromolecule biosynthetic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp407|Thapsigargin 0.005μM R07 exp407]]|-2.36| |[[:results:exp6|Bortezomib 0.005μM R00 exp6]]|-2.04| |[[:results:exp517|Quercetin 20μM R08 exp517]]|-2.01| |[[:results:exp260|ABT-702 0.1μM R06 exp260]]|-1.82| |[[:results:exp442|Ibrutinib 10μM R08 exp442]]|-1.79| No correlation found to any other genes in chemogenomics.
