Enables

This protein enables 3 target(s):

Target	Category	Definition
polypeptide N-acetylgalactosaminyltransferase activity	molecular function	Catalysis of the reaction: UDP-N-acetyl-D-galactosamine + polypeptide = UDP + N-acetyl-D-galactosaminyl-polypeptide. This reaction is the modification of serine or threonine residues in polypeptide chains by the transfer of a N-acetylgalactose from UDP-N-acetylgalactose to the hydroxyl group of the amino acid; it is the first step in O-glycan biosynthesis. [EC:2.4.1.41, ISBN:0879695595]
manganese ion binding	molecular function	Binding to a manganese ion (Mn). [GOC:ai]
carbohydrate binding	molecular function	Binding to a carbohydrate, which includes monosaccharides, oligosaccharides and polysaccharides as well as substances derived from monosaccharides by reduction of the carbonyl group (alditols), by oxidation of one or more hydroxy groups to afford the corresponding aldehydes, ketones, or carboxylic acids, or by replacement of one or more hydroxy group(s) by a hydrogen atom. Cyclitols are generally not regarded as carbohydrates. [GOC:mah]

Located In

This protein is located in 7 target(s):

Target	Category	Definition
Golgi membrane	cellular component	The lipid bilayer surrounding any of the compartments of the Golgi apparatus. [GOC:mah]
extracellular region	cellular component	The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite. [GOC:go_curators]
endoplasmic reticulum membrane	cellular component	The lipid bilayer surrounding the endoplasmic reticulum. [GOC:mah]
membrane	cellular component	A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. [GOC:dos, GOC:mah, ISBN:0815316194]
Golgi cisterna membrane	cellular component	The lipid bilayer surrounding any of the thin, flattened compartments that form the central portion of the Golgi complex. [GOC:ecd, GOC:mah]
endoplasmic reticulum-Golgi intermediate compartment membrane	cellular component	The lipid bilayer surrounding any of the compartments of the endoplasmic reticulum (ER)-Golgi intermediate compartment system. [GOC:mah, GOC:pr, PMID:16723730]
perinuclear region of cytoplasm	cellular component	Cytoplasm situated near, or occurring around, the nucleus. [GOC:jid]

Involved In

This protein is involved in 5 target(s):

Target	Category	Definition
protein O-linked glycosylation	biological process	A protein glycosylation process in which a carbohydrate or carbohydrate derivative unit is added to a protein via the hydroxyl group of peptidyl-serine, peptidyl-threonine, peptidyl-hydroxylysine, or peptidyl-hydroxyproline, or via the phenol group of peptidyl-tyrosine, forming an O-glycan. [GOC:pr, ISBN:0879695595, RESID:AA0153, RESID:AA0154, RESID:AA0155, RESID:AA0157, RESID:AA0212]
O-glycan processing	biological process	The stepwise addition of carbohydrate or carbohydrate derivative residues to the initially added O-linked residue (usually GalNAc) to form a core O-glycan structure. [GOC:mah, GOC:pr, PMID:10580130]
protein O-linked glycosylation via serine	biological process	The glycosylation of protein via the O3 atom of peptidyl-serine, forming O3-glycosyl-L-serine; the most common forms are N-acetylgalactosaminyl, mannosyl, galactosyl, and xylosyl serine. [RESID:AA0154]
protein O-linked glycosylation via threonine	biological process	The glycosylation of protein via the O3 atom of peptidyl-threonine, forming O3-glycosyl-L-threonine; the most common forms are N-acetylgalactosaminyl, mannosyl, and galactosyl threonine. [RESID:AA0155]
viral protein processing	biological process	Any protein maturation process achieved by the cleavage of a peptide bond or bonds within a viral protein. [GOC:bf, GOC:jl, ISBN:0781702534]
