  • 常规说明


    Lck (p56lck), a member of the Src family of non-receptor tyrosine protein kinases, is expressed predominantly in T cells. Lck function is critical both for T cell development in the thymus and activation of mature T cells in the periphery by antigen. The activity of Lck is known to be regulated by phosphorylation of two conserved tyrosine residues, Tyr-505 (equivalent to Tyr-529 in c-Src) and Tyr-394 (equivalent to Tyr-418 in c-Src).

靶标

  • 功能Tyrosine kinase that plays an essential role for the selection and maturation of developing T-cell in the thymus and in mature T-cell function. Is constitutively associated with the cytoplasmic portions of the CD4 and CD8 surface receptors and plays a key role in T-cell antigen receptor(TCR)-linked signal transduction pathways. 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, and thereby recruits the associated LCK to the vicinity of the TCR/CD3 complex. LCK then phosphorylates tyrosines residues within the immunoreceptor tyrosines-based activation motifs (ITAMs) in the cytoplasmic tails of the TCRgamma chains and CD3 subunits, initiating the TCR/CD3 signaling pathway. In addition, contributes to signaling by other receptor molecules. Associates directly with the cytoplasmic tail of CD2, and upon engagement of the CD2 molecule, LCK undergoes hyperphosphorylation and activation. Also plays a role in the IL2 receptor-linked signaling pathway that controls T-cell proliferative response. Binding of IL2 to its receptor results in increased activity of LCK. Is expressed at all stages of thymocyte development and is required for the regulation of maturation events that are governed by both pre-TCR and mature alpha beta TCR. Phosphorylates RUNX3.
  • 组织特异性Expressed specifically in lymphoid cells.
  • 疾病相关Note=A chromosomal aberration involving LCK is found in leukemias. Translocation t(1;7)(p34;q34) with TCRB.
  • 序列相似性Belongs to the protein kinase superfamily. Tyr protein kinase family. SRC subfamily.
    Contains 1 protein kinase domain.
    Contains 1 SH2 domain.
    Contains 1 SH3 domain.
  • 结构域The SH2 domain mediates interaction with SQSTM1. Interaction is regulated by Ser-59 phosphorylation.
  • 翻译后修饰Phosphorylated on Tyr-394, which increases enzymatic activity (By similarity). Phosphorylated on Tyr-505, which decreases activity.
  • 细胞定位Cytoplasm. Cell membrane. Present in lipid rafts in an unactive form.

  • 形式This protein is known to be similar in amino acid sequence to HCK (P08631), FYN (P06241), YES1 (P07947), SRC (P12931), and LYN (P07948). Therefore, cross-reactivity with these homologous proteins may be observed. We would be happy to provide immunogen alignment information upon request.
