Entrez ID 2645
Gene name Glucokinase
Gene symbol GCK
Synonyms (NCBI Gene)
FGQTL3GKGLKHHF3HK4HKIVHXKPLGLKMODY2PNDM1
Chromosome 7
Chromosome location 7p13
Summary This gene encodes a member of the hexokinase family of proteins. Hexokinases phosphorylate glucose to produce glucose-6-phosphate, the first step in most glucose metabolism pathways. In contrast to other forms of hexokinase, this enzyme is not inhibited b
