SRC Tyrosine Kinase Activation Pathway

Progression through the cell cycle is accompanied by activation of the proto-oncogene c-Src, a protein tyrosine kinase. Overexpression of Src leads to tyrosine phosphorylation of multiple protein substrates and cellular transformation. During interphase the Src protein folds back upon itself to stay in the inactive state, with a phosphotyrosine residue in one domain at Tyrosine 529 bound by an SH2 domain in the same protein. Activation of c-Src involves protein-tyrosine phosphatase alpha (PTP-alpha, or RPTP-alpha), a transmembrane protein with a cytoplasmic phosphatase domain. A variety of evidence has indicated that PTP-alpha dephosphorylates c-Src at Tyr529, allowing Src to open up and become activated, and that this activation occurs in association with mitosis. To activate Src, PTP-alpha must first open up the folded Src through binding itself to the phosphorylated Src domain, a process blocked by binding of Grb-2 to PTP-alpha at phosphorylated Tyr789. PTP-alpha phosphorylated at Tyr789 also binds to the Src SH2 domain, causing the Src structure to open at Src Tyr529 to become available for dephosphorylation. During mitosis the mitotic kinase Cdc-2 phosphorylates Src, along with other cellular substrates, and in so doing makes Src more prone to PTP-alpha dephosphorylation and activation. The activity of PTP-alpha toward Src is also regulated by phosphorylation of PTP-alpha by protein kinase C at serines 180 and 204, releasing the inhibition of PTP-alpha by Grb-2. In the normal cell cycle, Src activity is down-regulated after cell division through dephosphorylation by protein phosphatases and phosphorylation by Csk (C-terminal src kinase) and PTP-alpha dephosphorylation returns the cycle to its interphase condition. The regulation of Src activity during mitosis demonstrates how protein phosphorylation can shift the delicate equilibrium of molecular interactions and cellular responses. (BioCarta) [from NCI]

CSK Protein Kinase Activation Pathway

Interaction of T cell receptor with specific antigen in the context of MHC II activates a signal transduction pathway that leads to T cell activation. In the T cell receptor signaling pathway, the src family kinases Lck and Fyn are activated to phosphorylate proteins in the T cell receptor complex which recruit and activate the ZAP70 kinase. The activation of ZAP70 phosphorylates downstream targets that activate MAP kinase pathways and cause T cell activation. The CD45 phosphorylase also plays a role in T cell receptor signaling, dephosphorylated Lck and Fyn to activate them. Other factors modulate T cell receptor activation. Csk (COOH-terminal Srk kinase) phosphorylates Lck and deactivates it, opposing the action of CD45. The phosphorylation of Lck by Csk inhibits T cell receptor signaling and inhibits T cell activation. Csk activity is regulated in T cells by PKA, the cAMP-dependent protein kinase activated by the second messenger cAMP. The activity of Csk also appears to depend on other factors such as CBP, which recruits Csk to the plasma membrane in lipid rafts where other signaling factors such the T cell receptor complex are localized. CBP also directly activates Csk. (BioCarta) [from NCI]
