Required for the fusion of plasma membranes and early endosomes. Contributes to the regulation of filopodia extension. Binds EEA1. Interacts with RIN1 and GAPVD1, which regulate its pathway, probably by acting as a GEF. Interacts with ALS2CL, RABEP1, SUN2, ZFYVE20 and RUFY1. Interacts with SGSM1 and SGSM3. Interacts with PIK3CB. Regulated by guanine nucleotide exchange factors (GEFs) which promote the exchange of bound GDP for free GTP. Belongs to the small GTPase superfamily. Rab family. Note: This description may include information from UniProtKB.
