The first incubation was 30 min, whereas primary and secondary antibody reactions were 60 min each. Occlusion negative plaques were picked and seeded onto 2. However, similar fusion containing caveolin residues did not show any interaction.


These observations suggest that caveolin better recognizes the inactive conformation of c-Src, and thus, c-Src tyrosine kinase activity could be normally repressed by an interaction with caveolin. Read more about the condition.

One aliquot was subjected to an immune complex kinase assay see below.

Protein-tyrosine kinases play an essential role in the regulation of cellular growth control and differentiation. Quantitation of these experiments Fig. Acta Reviews in Cancerin press. Frequently bought together Feedback on our suggestions – Frequently bought together. This item fits below version 291190 of 21990 vehicle:.

Thus, it appears that caveolin prefers the inactive conformation of Src. Anti-Src-immunoprecipitates from T cells co-transfected with c-Src and caveolin were washed twice with kinase reaction buffer 20 m M Hepes, pH 7.

Cell Culture Insect Sf21 cells were provided by Dr. This differential effect was also observed when these three peptides were used xs evaluate their effects on the sd activity of hetero-trimeric G-proteins. Caveolin peptides were designed based on the protein sequence of the N-terminal domain of canine caveolin.


92190 is not phosphorylated when c-Src is inactive and is phosphorylated when c-Src is active 38 Because mutations in the extreme C terminus, the kinase domain, the SH2 domain, or the SH3 domain can constitutively activate c-Src, this activation may be mediated a conformational change in one of these regions These results with v-Src further demonstrate the specificity of the interaction between c-Src and caveolin.

Caveolae are plasma membrane specializations present in most cell types. Also, caveolin co-immunoprecipitates with c-Src when using antibodies directed against c-Src bottom panel.

Section solely to indicate this fact.

Fast and safe postage. In contrast, recombinant overexpression of wild-type c-Src does not result in efficient cell transformation or increased tyrosine phosphorylation, indicating that the tyrosine kinase activity of c-Src is normally repressed 37 These experiments were performed at least three times independently in duplicate. Quantitation of these experiments is provided in C.

Go to My Garage. Thus, our current studies imply that caveolin is a potent inhibitor of c-Src es perhaps other Src family tyrosine kinases.

This item will post to United Statesbut the seller hasn’t specified postage options. These results demonstrate that tyrosine phosphorylation of this caveolin sequence residues is not required for its inhibitory activity toward c-Src.

For guaranteed fitment please contact us with vehicle details so we can help ensure this part fits your vehicle – we aim to respond within 2 working hours. Recently, two caveolin-related proteins caveolin-2 and caveolin-3 have been identified and cloned; caveolin has been retermed caveolin Similarly, v-Src was constructed as a recombinant baculovirus Slides were mounted with Slow-Fade anti-fade reagent and observed under a Bio-Rad MR confocal fluorescence microscope.

After binding, extensive washing, and elution with reduced glutathione, bound Src was visualized by immunoblot analysis as in Fig. Thus, in vitro auto-phosphorylation of c-Src serves as a measure of its auto-activation. See compatible vehicles Quantity: Caveolin peptides were examined for their effect on the autophosphorylation of purified recombinant Fyn kinase in vitro.

Returns received by us 30 days or more after the date of despatch will not be accepted unless specifically agreed beforehand. Co-expression with caveolin dramatically suppressed the tyrosine kinase activity of c-Src as measured via an immune complex kinase assay.

Construction and Purification of Glutathione S-Transferase-Caveolin Fusion Proteins The construction, expression, and purification of GST-caveolin 1 fusion proteins were as we described previously 2425 Prev Next Table of Contents.
