Anti-RGS3抗体(ab2564)

RGS 3 (Regulator of G protein Signaling 3) is widely expressed in many tissues and cells. The protein contains an RGS domain near the carboxy terminus that serves as a GTPase activating protein (GAP). RGS 3 negatively regulates the activation of Gialpha and G alpha q. A truncated RGS 3 (RGS 3T), with its N-terminal 313 residues removed, has been shown to negatively regulate acenylyl cyclase and PLC. RGS 3T may be localized in the nucleus and RGS 3 is found in cytoplasm. Translocation to the membrane is important for the RGS proteins to interact with heterotrimeric G proteins.

Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.

Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.

We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.

In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.

We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.

Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.
