Specifications

Product Data
Clone Name	M332
Applications	IP, WB
Recommend Dilution	WB: 1:1000
Reactivity	Human, Rat, Mouse
Host	Mouse
Immunogen	Clone (M332) was generated from a recombinant sequence containing the C-terminal half of mouse Crk II. This sequence has high homology to human and rat Crk II.
Specificity	This antibody detects a 40 kDa* protein corresponding to the molecular mass of Crk II on SDS-PAGE immunoblots of rat PC12 and human Jurkat cells.
Formulation	PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol
Concentration	lot specific
Purification	Protein A Purified
Conjugation	Unconjugated
Storage Condition	Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
Predicted Protein Size	40
Database Link	UniProt ID P46108
Background	The Crk family of adaptor proteins (Crk I, Crk II and CrkL) are Src Homology 2 (SH2) and Src Homology 3 (SH3) domain-containing proteins that form protein complexes important for transmiting signals downstream of tyrosine kinases. Both Crk II and CrkL are composed of a single SH2 domain, followed by two tandem SH3 domains. Crk II is also alternatively spliced to a minor product, Crk I, which is structurally and functionally more similar to the v-Crk oncogene. Both Crk II and CrkL are ubiquitously expressed and their SH domains are highly homologous, however both are required for mouse development and have distinct non-overlapping phenotypes in knockout mice. Phosphorylation may be important for regulating Crk activity. Crk II Tyr-221 (CrkL Tyr-207) phosphorylation is a negative regulatory site, while Crk Tyr-251 phosphorylation in the SH3 domain is a positive regulatory site. EGF stimulation induces phosphorylation of Tyr-251, which increases binding of Crk to the SH2 domain of Abl, and promotes transactivation of Abl.
Note	Protein G purified tissue culture supernatant.
