Glycoprotein-N-acetylgalactosamine 3-beta-galactosyltransferase 1

Gene

C1GALT1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Glycosyltransferase that generates the core 1 O-glycan Gal-beta1-3GalNAc-alpha1-Ser/Thr (T antigen), which is a precursor for many extended O-glycans in glycoproteins. Plays a central role in many processes, such as angiogenesis, thrombopoiesis and kidney homeostasis development.

Catalytic activityi

UDP-alpha-D-galactose + glycoprotein N-acetyl-D-galactosamine = UDP + glycoprotein D-galactosyl-(1->3)-N-acetyl-D-galactosamine.1 Publication

Miscellaneousi

Miscellaneous

Aberrant O-galactosylation of IgA1 molecules plays a role in the development and progression of IgA nephropathy (IgAN). Genetic interactions of C1GALT1 and ST6GALNAC2 variants influence IgA1 O-glycosylation, disease predisposition, and disease severity, and may contribute to the polygenic nature of IgAN.
