Opis

Opis ogólny

Tyrosine-protein kinase Lck (UniProt: P06239; also known a EC:2.7.10.2, Leukocyte C-terminal Src kinase, LSK, Lymphocyte cell-specific protein-tyrosine kinase, Protein YT16, Proto-oncogene Lck, T cell-specific protein-tyrosine kinase, p56-LCK) is encoded by the LCK gene (Gene ID: 3932) in human. Lck is a non-receptor tyrosine kinase that is specifically expressed in lymphoid cells. Its protein kinase domain is localized to amino acids 245-498. It plays an essential role in the selection and maturation of developing T-cells in the thymus and also plays a role in function of mature T-cells. It is reported to constitutively associate with the cytoplasmic region of the CD4 and CD8 receptors. It also plays a role in T-cell antigen receptor (TCR)-linked signaling. Association of the TCR with a peptide antigen-bound MHC complex facilitates the interaction of CD4 and CD8 with MHC class II and class I molecules, respectively. This results in recruitment of Lck to the vicinity of the TCR/CD3 complex where Lck can phosphorylate tyrosine residues within the immunoreceptor tyrosine-based activation motifs (ITAM) of the cytoplasmic tails of the TCR- chains and CD3 subunits that initiates the TCR/CD3 signaling. Once stimulated, the TCR recruits the tyrosine kinase ZAP70 that becomes phosphorylated and activated by Lck. Following this, a large number of signaling molecules are recruited, ultimately leading to lymphokine production. Autophosphorylation of Lck on tyrosine 394 increases its enzyme activity, whereas phosphorylation on tyrosine 505 by C-terminal Src kinase (CSK) results in a reduction in its activity.
