RAPGEF1 encodes a human guanine nucleotide exchange factor. It transduces signals from CRK by binding the SH3 domain of CRK, and activating several members of the Ras family of GTPases. This signaling cascade that may be involved in apoptosis, integrin-mediated signal transduction, and cell transformation. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some variants has not been determined. 蛋白别名为：RAPGEF1; GRF2; Rap guanine nucleotide exchange factor 1; CRK SH3-binding GNRP; Guanine nucleotide-releasing factor 2; Protein C3G;基因ID为：2889；蛋白质ID:Q13905
IHC-p，ELISA补充：最优的抗体稀释比例需要基于客户实验进行优化.建议的起始稀释比例如下: IHC-p: 1:100-1:300, ELISA: 1:5000. Not yet tested in other applications.
