[[http://www.uniprot.org/uniprot/RPGF4_MOUSE RPGF4_MOUSE]] Guanine nucleotide exchange factor (GEF) for RAP1A, RAP1B and RAP2A small GTPases that is activated by binding cAMP. Seems not to activate RAB3A. Involved in cAMP-dependent, PKA-independent exocytosis through interaction with RIMS2.<ref>PMID:11056535</ref> [[http://www.uniprot.org/uniprot/RAP1B_HUMAN RAP1B_HUMAN]] GTP-binding protein that possesses intrinsic GTPase activity. Contributes to the polarizing activity of KRIT1 and CDH5 in the establishment and maintenance of correct endothelial cell polarity and vascular lumen. Required for the localization of phosphorylated PRKCZ, PARD3 and TIAM1 to the cell junction.<ref>PMID:20332120</ref> <ref>PMID:18660803</ref>
