The functions of src family protein-tyrosine kinases are thought to be regulated negatively by the phosphorylation of highly conserved tyrosine residues close to their carboxyl termini. Recently we have purified and cloned a protein-tyrosine kinase (designated as CSK) that can specifically phosphorylate...

Protein tyrosine kinases of the Src family are negatively regulated by phosphorylation in the C-terminal tail of the molecule. A different protein tyrosine kinase, Csk, is largely responsible for this regulation. The phosphorylated tail of c-Src engages with the SH2 domain in a conformation that...
Csk (C-terminal Src kinase), a protein tyrosine kinase, consisting of the Src homology 2 and 3 (SH2 and SH3) domains and a catalytic domain, phosphorylates the C-terminal tail of Src-family members, resulting in downregulation of the Src family kinase activity. The Src family kinases share...
Src shares with the other Src Family Kinases (SFKs) a common modular structure formed by the membrane-anchoring SH4 region followed by an intrinsically disordered region (IDR) named unique domain (UD), and the SH3, SH2, and kinase domains [2]. Our knowledge of Src regulation relies on ...
The phenotypes of CHO-Ras-SHPS-1-FLAG-JM cells resemble those of cultured cells that overexpress wild-type Csk (47). Although Csk was shown to regulate the activity of Src family kinases negatively, overexpression of Csk also increased the tyrosine phosphorylation of paxillin and FAK triggered ...
110 The effects of these bile acids were mediated by the Src family kinases and was abolished by EGF treatment.110 A study on prematurely weaned piglets reported that administration of CDCA improves the gut barrier protection by inducing expression of ZO-1 and reducing expression of TNF-α, IL...
There are 9 Src family kinases, and they have a conserved domain arrangement (SH3-SH2-kinase) that is necessary for regulation. The basal activity of c-Src is normally kept low due to phosphorylation by C-terminal Src kinase (Csk). This regulatory relationship has been conserved throughout ...
Negative regulation of T-cell receptor signalling by tyrosine protein kinase p50csk T-cell antigen receptor (TCR) signalling has been shown to involve two classes of tyrosine protein kinases: the Src-related kinases p56(lck) and p59(fyr), ... LML Chow,M Fournel,D Davidson,... - 《Natur...
of the Src family of protein tyrosine kinases upregulate NMDAR function, thereby gating the production of NMDAR-dependent synaptic potentiation. Src family kinases (SFKs) are a crucial point of convergence for signalling pathways that enhance NMDAR activity, so that SFKs act as a molecular hub for...
