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. This protein, a type II membrane protein found in the Golgi, is also required for the synthesis of the bacterial verotoxins receptor. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2015]
Forensic Context
A study in mice demonstrated that burn injury to the hind paw induced transcriptomic remodeling in the primary somatosensory cortex, where the A4GALT gene was specifically upregulated one hour post-injury [Erdei et al. DOI:10.3390/ijms26083538].
