GRIPAP1 Protéines

This gene encodes a guanine nucleotide exchange factor for the Ras family of small G proteins (RasGEF). In brain studies, the encoded protein was found with the GRIP/AMPA receptor complex. Multiple alternatively spliced transcript variants have been described that encode different protein isoforms\; however, the full-length nature and biological validity of all of these variants have not been determined.[provided by RefSeq, Nov 2009].
