Description_x000D_ Immunogen_x000D_ Synthetic peptide containing a sequence corresponding to a region within amino acids 528 and 537 of RIC8A according to NP_068751_x000D_ Application_x000D_ Suggested starting dilutions are as follows: IHC-P: 1:100-1:1000, WB: 1:500-1:3000. Not yet tested in other applications. Optimal working dilutions should be determined experimentally by the end user._x000D_ Physical form_x000D_ 0.1M Tris, 0.1M Glycine, 10% Glycerol (pH7). 0.01% Thimerosal was added as a preservative._x000D_ Biochem/physiol Actions_x000D_ Guanine nucleotide exchange factor (GEF), which can activate some, but not all, G-alpha proteins. Able to activate GNAI1, GNAO1 and GNAQ, but not GNAS by exchanging bound GDP for free GTP. Involved in regulation of microtubule pulling forces during mitotic movement of chromosomes by stimulating G(i)-alpha protein, possibly leading to release G(i)-alpha-GTP and NuMA proteins from the NuMA-GPSM2-G(i)-alpha-GDP complex (By similarity). Also acts as an activator for G(q)-alpha (GNAQ) protein by enhancing the G(q)-coupled receptor-mediated ERK activation._x000D_ Features and Benefits_x000D_ Evaluate our antibodies with complete peace of mind.
