Galactokinase 2; GalNAc Kinase; EC 2.7.1.157; GK2; N-Acetylgalactosamine Kinase; EC 2.7.1

This gene encodes a highly efficient N-acetylgalactosamine (GalNAc) kinase, which has galactokinase activity when galactose is present at high concentrations. The encoded protein is a member of the GHMP kinase family. Alternative splicing results in multiple transcript variants.
