| Short Name | RasGRF1 |
| description | RasGRF1 belong to the RasGRF family. It regulates both Ras and Rac signalling pathways []. It has been implicated in memory formation, postnatal growth, glucose homeostasis and photoreception [].RasGRF is a Ras family guanine nucleotide exchange factor sharing homology with Saccharomyces cerevisiae Cdc25 that stimulates nucleotide exchange on S. cerevisiae RAS []. RasGRF N-terminal region contains a Dbl homology (DH) domain which is generally present in GEFs for the Rho family of small G proteins, whereas the C-terminal Cdc25-related domain is linked to Ras GTPase signalling []. The presence of regulatory domains for Rho and Ras GTPases implicates the role of RasGRF in the control of the both pathways []. Two RasGRF, RasGRF1 and 2, have been identified in mammals []. Their function can be inhibited by its interaction with Cdc42 in its inactive GDP bound form. Reciprocally, the effects of Cdc42 on cytoskeletal dynamics can be inhibited by RasGRF1/2 []. |
