NCIt definition : Human HCK wild-type allele is located within 20q11-q12 and is approximately 50 kb
in length. This allele, which encodes tyrosine-protein kinase HCK protein, is involved
in signal transduction.;
NCIt note : The HCK gene is expressed primarily in hematopoietic cell types, especially those
of myeloid lineage and particularly in mature granulocytes and monocytes. Tyrosine-protein
kinase HCK protein may play a role in activation of the respiratory burst, neutrophil
migration and degranulation of neutrophils. Two isoforms of this protein, which differ
in subcellular localization, are produced by alternate translation initiation. Activation
of HCK protein facilitates the replication of human immunodeficiency virus type 1.;
