Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Growth factor active in angiogenesis and endothelial cell growth, stimulating their proliferation and migration. It binds to the receptor FLT1/VEGFR-1. Isoform PlGF-2 binds NRP1/neuropilin-1 and NRP2/neuropilin-2 in a heparin-dependent manner.
Subunit structure	Antiparallel homodimer; disulfide-linked. Also found as heterodimer with VEGFA/VEGF. Isoform PlGF-3 is found both as homodimer and as monomer.
Subcellular location	Secreted. Note: The three isoforms are secreted but PlGF-2 appears to remain cell attached unless released by heparin.
Tissue specificity	While the three isoforms are present in most placental tissues, PlGF-2 is specific to early (8 week) placenta and only PlGF-1 is found in the colon and mammary carcinomas.
Domain	Isoform PlGF-2 contains a basic insert which acts as a cell retention signal.
Post-translational modification	N-glycosylated.
Sequence similarities	Belongs to the PDGF/VEGF growth factor family.
