Protein Structure

UniProt Annotation

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. Also promotes cell tumor growth. {ECO:0000269PubMed:21215706}.

Subcellular Localization

Secreted. Note=The three isoforms are secreted but PlGF-2 appears to remain cell attached unless released by heparin.

Disease Associations

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.
