| Specificity / Sensitivity | Phospho-Ras-GRF1 (Ser916) Antibody detects transfected levels of Ras-GRF1 only when phosphorylated at serine 916. This antibody does not cross-react with phosphorylated Ras-GRF2. |
| Source / Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding serine 916 of mouse Ras-GRF1. Antibodies are purified by protein A and peptide affinity chromatography. Western Blotting
Western blot analysis of extracts from COS cells, untransfected (lane 1) or transfected with either wild-type (lanes 2 and 3) or Ala916 mutant (lanes 4 and 5) Ras-GRF1, using Phospho-Ras-GRF1 (Ser916) Antibody (upper) or Ras-GRF1 Antibody #3322 (lower). Transfected COS cells were untreated or treated forskolin as indicated.(Triple HA-tagged Ras-GRF1 expressing plasmids provided by Dr. R. Mattingly, Dept. of Pharmacology, Wayne State University, Michigan.) |
| Background | Ras activity is regulated by GAP (GTPase activating proteins) and GEFs (guanine nucleotide exchange factors). Ras-GRF1 (also known as CDC25Mm) is neuronal RasGEF and is regulated by heterotrimeric G proteins and calcium influx (1,2). Binding to calmodulin and phosphorylation stimulate Ras-GRF1 activity (1,2). Multiple PKA phosphorylation sites on Ras-GRF have been identified. Phosphorylation on the two major sites, Ser54 and Ser822, inhibits Ras-GRF activity (3). Carbachol (a muscarinic agonist)-induced phosphorylation on Ser916 is essential but not sufficient for maximal Ras-GRF activity (4). It has been reported that Ras-GRF1 also shows GEF activity toward Rac after phosphorylation by the tyrosine kinase Src (5). |
