======= A4GALT =======
== Gene Information ==
* **Official Symbol**: A4GALT
* **Official Name**: alpha 1,4-galactosyltransferase (P blood group)
* **Aliases and Previous Symbols**: N/A
* **Entrez ID**: [[https://www.ncbi.nlm.nih.gov/gene/?term=53947|53947]]
* **UniProt**: [[https://www.uniprot.org/uniprot/Q9NPC4|Q9NPC4]]
* **Interactions**: [[https://thebiogrid.org/search.php?search=A4GALT&organism=9606|BioGRID]]

* **OMIM**: [[https://omim.org/entry/607922|Open OMIM]]
== Function Summary ==
* **Entrez 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. 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].
* **UniProt Summary**: Necessary for the biosynthesis of the Pk antigen of blood histogroup P. Catalyzes the transfer of galactose to lactosylceramide and galactosylceramide. Necessary for the synthesis of the receptor for bacterial verotoxins.
