Src Protein, Mouse, Recombinant (His & GST Tag)

Proto-oncogene tyrosine-protein kinase SRC is a hydrophobic protein belonging to the SRC family kinase including nine members that is a family of non-receptor tyrosine kinases. SRC protein may exist in different forms: C-SRC and V-SRC. C-SRC is only activated under certain circumstances where it is required such as growth factor signaling, while V-SRC is constitutively active as opposed to normal SRC (C-SRC) . Thus, V-SRC is an instructive example of an oncogene protein kinase whereas C-SRC is a proto-oncogene protein kinase. Inhibition of SRC with NR2A tyrosine phosphorylation mediated by PSD-95 may contribute to the lithium-induced downregulation of NMDA receptor function and provide neuroprotection against excitotoxicity.

1. The specific activity was determined to be > 80 nmol/min/mg using poly [Glu, Tyr] 4:1 as substrate. 2. Measured by its binding ability in a functional ELISA. Immobilized recombinant Mouse SRC at 2 μg/ml (100 μl/well) can bind biotinylated human PTPRA (aa 174-793) with a linear range of 0.032-0.8 μg/ml.

Supplied as sterile 20mM Tris, 500mM NaCl, 10% glycerol, pH 8.0 Please contact us for any concerns or special requirements. Please refer to the specific buffer information in the hard copy of CoA.

The recombinant mouse SRC/GST chimera consists of 773 amino acids and has a calculated molecular mass of 87.7 kDa. It migrates as an approximately 80 kDa band in SDS-PAGE under reducing conditions.

Kinases are highly recommended to be shipped at frozen temperature with blue ice or dry ice. Shipment made at ambient temperature may seriously affect the activity of the ordered products. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
