一般說明
The signalling in T cells is mediated by receptor and non-receptor protein tyrosine kinases (PTK). Among the family of non-receptors PTK, Lck is a lymphoid-specific cytosolic PTK essential for T-cell development and function. Lck is essential for selection and maturation of developing T cells in the thymus. It plays a significant role in T-cell receptors mediated signalling by constitutive association with CD4 and CD8 receptors. In addition, Lck undergoes phosphorylation and activation by association with CD2 molecule. Lck also plays a role in T-cell proliferation in response to IL-2 receptor pathway. The activity of Lck is known to be regulated by phosphorylation of two conserved tyrosine residues, tyrosine 505 (equivalent to tyrosine 529 in c-Src) and tyrosine 394 (equivalent to tyrosine 418 in c-Src). Phosphorylation at Tyr505 stabillizes Lck and renders it biologically inactive.
Anti-phospho Lck (pTyr505) specifically recognizes human Lck (pTyr505). Mouse (100% homology) and chicken (91.7% homology) are expected to react.

免疫原
synthetic phosphopeptide derived from the region of Lck that is phosphorylated on tyrosine 505. Rat and mouse have 100% homology with human.
應用
A working concentration of 0.1-1.0 μg/mL is recommended for detection of human Lck protein by immunoblotting.
外觀
Solution in phosphate buffer, pH 7.4, with 1 mg/mL BSA (IgG and protease free) and 0.05% sodium azide.
準備報告
The antibody is preadsorbed to remove any reactivity towards a non-phosphorylated Lck.

Recent evidence supports the view that p56lck, a non-receptor protein tyrosine kinase, serves as the signaling element that 'senses' synthesis of a functional T-cell receptor beta chain, thereby promoting thymocyte maturation. Here, Steven Anderson and Roger Perlmutter review current data

Protein tyrosine kinases (PTKs) are critically involved in signaling pathways that regulate cell growth, differentiation, activation, and transformation. It is not surprising, therefore, that viruses acquire effector molecules targeting these kinases to ensure their own replication and/or persistence. This review

We studied the extent of functional linkage between CD3 sigma and p56lck in pre-TCR-dependent thymocyte development. Differentiation of DN to DP cells was examined by treatment of RAG2/CD3 sigma and RAG1/p56lck double-deficient mice with anti-CD3 epsilon antibodies. The results suggest
