CC -!- FUNCTION: Induces angiogenesis probably through VEGF receptor
CC (KDR/VEGFR-2) signaling, as well as drastic hypotension. The
CC hypotension is mediated by nitric oxide, which is produced by VEGF-
CC activated endothelium NO synthase. May also induce capillary
CC permeability. {ECO:0000269|PubMed:14600159}.
CC -!- SUBUNIT: Homodimer; disulfide-linked. Interacts with VEGF receptor-2
CC (KDR) with high affinity, but not with VEGF receptor-1 (Flt-1), VEGF
CC receptor-3 (FLT4), and neuropilin-1 (NRP1).
CC {ECO:0000269|PubMed:14600159, ECO:0000269|PubMed:15542594}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:14600159}.
CC -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC {ECO:0000305|PubMed:14600159}.
CC -!- SIMILARITY: Belongs to the PDGF/VEGF growth factor family. Snake venom
CC VEGF subfamily. {ECO:0000305}.
