Target Information
LCK is a member of the Src-family tyrosine kinases, essential for signaling through the T-cell receptor (TCR) complex. Upon TCR activation, LCK phosphorylates ITAM motifs in the zeta subunits, enabling binding of ZAP70, which is subsequently phosphorylated and activated by LCK. This cascade leads to downstream signaling via adaptor LAT.
LCK localizes mainly to the plasma membrane but is also associated with the Golgi apparatus, potentially contributing to Raf activation under weak TCR stimulation. The protein contains N-terminal myristylation and palmitylation sites, a PTK domain, and SH2/SH3 domains mediating protein-protein interactions. LCK also regulates apoptosis induced by various stimuli, excluding death receptor pathways. Diseases associated with LCK include Immunodeficiency 22 and CD45 deficiency. Alternative splice variants produce different isoforms of the protein.
