General description
Research area: Cell Signaling
N-Terminal His6-tagged, recombinant, full-length, human Src.
Src proteins are non-receptor protein tyrosine kinases, that belong to the Src family of kinases. These proteins have a unique structure consisting of an N-terminal region with a 14-carbon myristoyl group, two Src homology domains (SH2 and SH3), a catalytic tyrosine-protein kinase domain (SH1), and a short C-terminal tail. The SH1 domain is catalytic in function, while the SH2 and SH3 domains are non-catalytic and regulatory in nature.
Product Source: Human c-src, expressed in Sf21 cells.
Application
The Src protein may be used to study the interaction between CD133 and Src protein and its effect on FAK phosphorylation and cell migration through in vitro kinase assay.
Biochem/physiol Actions
Src protein tyrosine kinases are involved in signaling pathways that control a plethora of cellular functions ranging from cell cycle, proliferation, differentiation, gene transcription, immune responses, apoptosis, etc. Upon its activation, Src phosphorylates and activates several other kinases Like MAPK (Mitogen-Activated Protein Kinase), p38, and ERK (Extracellular signal-regulated kinase). Activated MAPK (Mitogen-Activated Protein Kinase) regulates inflammation, cell development, differentiation and senescence. P38 is involved with the migration and survival of endothelial cells and extracellular signal-regulated kinase (ERK) promotes the proliferation and inflammation of endothelial cells. They play a key role in the regulation of cytoskeletal organization through the phosphorylation of substrates like Actin filament-associated protein 1 (AFAP1) and cortactin (CTTN). Src also plays a crucial role in maintaining cell adhesion, morphology, motility, and bone resorption by interacting with focal adhesion kinases. Src tyrosine kinase activity is upregulated in a variety of cancers including colon, lung, and pancreatic cancer, etc.
