Polypeptide N-acetylgalactosaminyltransferase 11

Gene

Organism

Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Polypeptide N-acetylgalactosaminyltransferase that catalyzes the initiation of protein O-linked glycosylation and is involved in left/right asymmetry by mediating O-glycosylation of NOTCH1. O-glycosylation of NOTCH1 promotes activation of NOTCH1, modulating the balance between motile and immotile (sensory) cilia at the left-right organiser (LRO). Polypeptide N-acetylgalactosaminyltransferases catalyze the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. Displays the same enzyme activity toward MUC1, MUC4, and EA2 than GALNT1. Not involved in glycosylation of erythropoietin (EPO) (By similarity).By similarity

Catalytic activityi

UDP-N-acetyl-alpha-D-galactosamine + polypeptide = UDP + N-acetyl-alpha-D-galactosaminyl-polypeptide.

Domaini

There are two conserved domains in the glycosyltransferase region: the N-terminal domain (domain A, also called GT1 motif), which is probably involved in manganese coordination and substrate binding and the C-terminal domain (domain B, also called Gal/GalNAc-T motif), which is probably involved in catalytic reaction and UDP-Gal binding.By similarity
The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity.By similarity
