Regulation of the Src family tyrosine kinase Blk through E6AP-mediated ubiquitination.
The Src family of nonreceptor tyrosine kinases are important regulators of a variety of cellular processes, including cytoskeletal organization, cell-cell contact, and cell-matrix adhesion. Activation of Src family kinases also can induce DNA synthesis and cellular proliferation; therefore, tight regulation of their kinase activities is important for the cell to maintain proliferative control. ...
متن کاملSrc protein-tyrosine kinase structure and regulation.
Src and Src-family protein kinases are proto-oncogenes that play key roles in cell morphology, motility, proliferation, and survival. v-Src (a viral protein) is encoded by the chicken oncogene of Rous sarcoma virus, and Src (the cellular homologue) is encoded by a physiological gene, the first of the proto-oncogenes. From the N- to C-terminus, Src contains an N-terminal 14-carbon myristoyl grou...
متن کاملEarly emergence of negative regulation of the tyrosine kinase Src by the C-terminal Src kinase.
Stringent regulation of tyrosine kinase activity is essential for normal cellular function. In humans, the tyrosine kinase Src is inhibited via phosphorylation of its C-terminal tail by another kinase, C-terminal Src kinase (Csk). Although Src and Csk orthologs are present across holozoan organisms, including animals and protists, the Csk-Src negative regulatory mechanism appears to have evolve...
متن کاملCasein kinase 2 (CK2)-mediated reduction of the activities of Src family tyrosine kinases in vitro.
The physiological correlation between casein kinase 2 (CK2) and two Src family tyrosine kinases (Src-TKs, Fyn and Src) was mainly investigated in vitro. It was found that (i) Thr-residues of these two Src-TKs were preferentially phosphorylated by CK2 using [gamma-32P]GTP as a phosphate donor; (ii) this phosphorylation was highly stimulated in the presence of poly-Arg; (iii) full phosphorylation...
متن کاملProtein tyrosine kinase regulation by ubiquitination: critical roles of Cbl-family ubiquitin ligases.
Protein tyrosine kinases (PTKs) coordinate a broad spectrum of cellular responses to extracellular stimuli and cell-cell interactions during development, tissue homeostasis, and responses to environmental challenges. Thus, an understanding of the regulatory mechanisms that ensure physiological PTK function and potential aberrations of these regulatory processes during diseases such as cancer ar...
