NCIt definition : Human LCK wild-type allele is located in the vicinity of 1p34.3 and is approximately
35 kb in length. This allele, which encodes proto-oncogene tyrosine-protein kinase
LCK protein, plays a role in T-cell antigen receptor-linked signal transduction pathways.
The LCK gene is associated with acute lymphoblastic leukemia and severe combined immunodeficiency.;
NCIt note : The LCK gene is expressed at all stages of thymocyte development. This gene is also
involved in natural killer cell-mediated cytotoxicity.;
