Lck (or lymphocyte-specific protein tyrosine kinase) is a 56 kDa protein that is found inside specialized cells of the immune system called lymphocytes. The Lck is a member of Src kinase family (SFK), it is important for the activation of the T-cell receptor signaling in both naive T cells and effector T cells. The … See more Lck is most commonly found in T cells. It associates with the cytoplasmic tails of the CD4 and CD8 co-receptors on T helper cells and cytotoxic T cells, respectively, to assist signaling from the T cell receptor (TCR) complex. T cells … See more The activity of the Lck can be positively or negatively regulated by the presence of other proteins such as the membrane protein CD146, the transmembrane tyrosine … See more Mutations in Lck are liked to a various range of diseases such as SCID (Severe combined immunodeficiency) or CIDs. In these pathologies, the dysfunctional activation of the lck … See more In resting T cells, Lck is constitutively inhibited by Csk phosphorylation on tyrosine 505. Lck is also inhibited by SHP-1 dephosphorylation on tyrosine 394. Lck can also be inhibited by Cbl ubiquitin ligase, which is part of the ubiquitin-mediated pathway. See more Lck is a 56-kilodalton protein. The N-terminal tail of Lck is myristoylated and palmitoylated, which tethers the protein to the plasma membrane of the cell. The protein furthermore … See more Lck tyrosine phosphorylates a number of proteins, the most important of which are the CD3 receptor, CEACAM1, ZAP-70, SLP-76, … See more Lck has been shown to interact with: • ADAM15, • CD2, • CD44, • CD4, • COUP-TFII, • DLG1, See more WebUSP11 forms a complex with USP7 to deubiquitinate the oncogenic lymphocyte cell-specific protein-tyrosine kinase (LCK) and enhance its activity. Impairment of LCK activity leads to increased glucocorticoid receptor (GR) expression and glucocorticoids sensitivity.

WebJan 1, 2024 · The lymphocyte-specific protein tyrosine kinase (LCK) belongs to the Src family of proto-oncogene kinases that regulate cell proliferation, motility, activation, and … WebMar 24, 2009 · 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. LCK also contributes to signaling by other receptor molecules. WebLck is a Src family protein tyrosine kinase and is expressed predominantly in T cells.
