Genet. 50:581-590(2018). CC -!- FUNCTION: Functions as a guanine nucleotide exchange factor (GEF), CC which activates Rap and Ras family of small GTPases by exchanging bound CC GDP for free GTP in a cAMP-dependent manner. Serves as a link between CC cell surface receptors and Rap/Ras GTPases in intracellular signaling CC cascades. Acts also as an effector for Rap1 by direct association with CC Rap1-GTP thereby leading to the amplification of Rap1-mediated CC signaling. Shows weak activity on HRAS. It is controversial whether CC RAPGEF2 binds cAMP and cGMP (PubMed:23800469, PubMed:10801446) or not CC (PubMed:10608844, PubMed:10548487, PubMed:11359771). Its binding to CC ligand-activated beta-1 adrenergic receptor ADRB1 leads to the Ras CC activation through the G(s)-alpha signaling pathway. Involved in the CC cAMP-induced Ras and Erk1/2 signaling pathway that leads to sustained CC inhibition of long term melanogenesis by reducing dendrite extension CC and melanin synthesis. Provides also inhibitory signals for cell CC proliferation of melanoma cells and promotes their apoptosis in a cAMP- CC independent nanner. Regulates cAMP-induced neuritogenesis by mediating CC the Rap1/B-Raf/ERK signaling through a pathway that is independent on CC both PKA and RAPGEF3/RAPGEF4. Involved in neuron migration and in the CC formation of the major forebrain fiber connections forming the corpus CC callosum, the anterior commissure and the hippocampal commissure during CC brain development. Involved in neuronal growth factor (NGF)-induced CC sustained activation of Rap1 at late endosomes and in brain-derived CC neurotrophic factor (BDNF)-induced axon outgrowth of hippocampal CC neurons. Plays a role in the regulation of embryonic blood vessel CC formation and in the establishment of basal junction integrity and CC endothelial barrier function. May be involved in the regulation of the CC vascular endothelial growth factor receptor KDR and cadherin CDH5 CC expression at allantois endothelial cell-cell junctions.

Interacts with CC KIDINS220 and NTRK1; the interactions occur after NGF stimulation (By CC similarity). Found in a complex, at least composed of KIDINS220, MAGI2, CC NTRK1 and RAPGEF2; the complex is mainly formed at late endosomes in a CC neuronal growth factor (NGF)-dependent manner. Interacts (via C- CC terminal domain) with NEDD4 (via WW domains); this interaction leads to CC ubiquitination and degradation via the proteasome pathway in a cAMP- CC independent manner. Interacts with MAGI1 isoform 3 (via PDZ domain). CC Interacts with ADRB1 (via C-terminal PDZ motif); the interaction is CC direct. Interacts (via Ras-associating domain) with RAP1A (via GTP- CC bound active form). Interacts weakly with HRAS (via GDP- and GTP-bound CC forms). Interacts (via C-terminal domain) with MAGI2 (via PDZ and WW CC domains). {ECO:0000250, ECO:0000269|PubMed:10548487, CC ECO:0000269|PubMed:10608844, ECO:0000269|PubMed:11168587, CC ECO:0000269|PubMed:11359771, ECO:0000269|PubMed:11598133, CC ECO:0000269|PubMed:12391161, ECO:0000269|PubMed:17724123}.
