Required for full OST catalytic activity in N-glycosylation (PubMed:26472760, PubMed:27974209). Involved in endoplasmic reticulum (ER) homeostasis in the colonic epithelium (By similarity). {ECO:0000250|UniProtKB:P61166, ECO:0000269|PubMed:26472760, ECO:0000269|PubMed:27974209}. |UPF0197| |oligosaccharyltransferase I complex| |protein N-linked glycosylation| |protein glycosylation| |macromolecule glycosylation| |glycosylation| |glycoprotein biosynthetic process| |glycoprotein metabolic process| |carbohydrate derivative biosynthetic process| |endoplasmic reticulum| |carbohydrate derivative metabolic process| |organonitrogen compound biosynthetic process| |cellular macromolecule biosynthetic process| |macromolecule biosynthetic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp419|Tunicamycin 0.04 to 0.075μM on day4 R07 exp419]]|1.7| |[[:results:exp531|THZ1 0.06μM R08 exp531]]|1.79| |[[:results:exp420|Tunicamycin 0.04 to 0.125μM on day4 R07 exp420]]|1.85| |[[:results:exp234|Ethanol 0.01 R05 exp234]]|1.86| |[[:results:exp418|Tunicamycin 0.04μM R07 exp418]]|1.89| ^Gene^Correlation^ |[[:human genes:r:rpn1|RPN1]]|0.477| |[[:human genes:d:ddost|DDOST]]|0.461| |[[:human genes:o:ost4|OST4]]|0.419| |[[:human genes:r:rpn2|RPN2]]|0.403| Global Fraction of Cell Lines Where Essential: 288/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|12/28| |blood|9/28| |bone|7/26| |breast|4/33| |central nervous system|25/56| |cervix|2/4| |colorectal|6/17| |esophagus|3/13| |fibroblast|0/1| |gastric|7/16| |kidney|14/21| |liver|12/20| |lung|32/75| |lymphocyte|6/16| |ovary|14/26| |pancreas|11/24| |peripheral nervous system|5/16| |plasma cell|4/15| |prostate|1/1| |skin|10/24| |soft tissue|4/9| |thyroid|1/2| |upper aerodigestive|9/22| |urinary tract|9/29| |uterus|4/5| == Essentiality in NALM6 == * **Essentiality Rank**: 1056 * **Expression level (log2 read counts)**: 5.01 {{:chemogenomics:nalm6 dist.png?nolink |}}
