Gene Summary

[ - ] NCBI Entrez Gene

Gene ID 53947 Official Symbol A4GALT
Locus N/A Gene Type protein-coding
Synonyms A14GALT; A4GALT1; P1; PK
Full Name alpha 1,4-galactosyltransferase
Description alpha 1,4-galactosyltransferase
Chromosome 22q11.2-q13.2
Also Known As CD77 synthase; GB3 synthase; P blood group (P one antigen); P(k) antigen synthase; P1/Pk synthase; UDP-galactose:beta-D-galactosyl-beta1-R 4-alpha-D-galactosyltransferase; alpha-1,4-N-acetylglucosaminyltransferase; alpha4Gal-T1; globotriaosylceramide synthase; lactosylceramide 4-alpha-galactosyltransferase
Summary The protein encoded by this gene catalyzes the transfer of galactose to lactosylceramide to form globotriaosylceramide, which has been identified as the P(k) antigen of the P blood group system. The encoded protein, which is a type II membrane protein found in the Golgi, is also required for the synthesis of the bacterial verotoxins receptor. [provided by RefSeq]
