Phosphorylated O-mannosyl trisaccharid is required for binding laminin G-like domain-containing extracellular proteins with high affinity. Elongates the glucuronyl-beta-1,4-xylose-beta disaccharide primer structure by adding repeating units [-3-Xylose-alpha-1,3-GlcA-beta-1-] to produce a heteropolysaccharide. Has a higher activity toward alpha-dystroglycan than LARGE. {ECO:0000269|PubMed:15661757, ECO:0000269|PubMed:15752776, ECO:0000269|PubMed:25138275}. |Glyco transf 8| |xylosyltransferase activity| |UDP-xylosyltransferase activity| |transferase activity, transferring glycosyl groups| |protein O-linked mannosylation| |muscle cell cellular homeostasis| |protein mannosylation| |glucuronosyltransferase activity| |mannosylation| |manganese ion binding| |protein O-linked glycosylation| |protein glycosylation| |macromolecule glycosylation| |glycosylation| |glycoprotein biosynthetic process| |anatomical structure homeostasis| |glycoprotein metabolic process| |carbohydrate derivative biosynthetic process| |Golgi membrane| |cellular homeostasis| |Golgi apparatus| |carbohydrate derivative metabolic process| |organonitrogen compound biosynthetic process| |homeostatic process| |cellular macromolecule biosynthetic process| |macromolecule biosynthetic process| \\ === CRISPR Data === No hits were found. ^Gene^Correlation^ |[[:human genes:r:rrm1|RRM1]]|0.402| Global Fraction of Cell Lines Where Essential: 0/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 12227 * **Expression level (log2 read counts)**: -0.06 {{:chemogenomics:nalm6 dist.png?nolink |}}
