Summary: Predicted to enable receptor ligand activity and receptor tyrosine kinase binding activity. Involved in several processes, including blood vessel development; maternal process involved in female pregnancy; and positive regulation of angiogenesis. Located in cell projection and extracellular space. Used to study several diseases, including ischemia (multiple); membranoproliferative glomerulonephritis; portal hypertension; retinal disease (multiple); and uremia. Biomarker of several diseases, including Caroli disease; artery disease (multiple); gastric ulcer; glomerulonephritis (multiple); and retinal disease (multiple). Human ortholog(s) of this gene implicated in hereditary lymphedema. Orthologous to human ANGPT2 (angiopoietin 2). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
