A4GALT Protein

A4GALT Protein Overview

A4GALT reagents

The A4GALT gene encodes alpha-1,4-galactosyltransferase (EC 2.4.1.228), an enzyme that transfers a galactose to the alpha-1,4 position of lactosylceramide to form globotriaosylceramide (GB3), also known as CD77. This glycolipid has been characterized on red blood cells as the P(k) antigen of the P1PK blood group system (111400). The A4GALT gene also synthesizes the P1 antigen of the P1PK blood group system (Iwamura et al., 2003, Thuresson et al., 2011).

A4GALT protein family

Belongs to the glycosyltransferase 32 family.
