Summary: Enables BH4 domain binding activity; MAP-kinase scaffold activity; and neuropilin binding activity. Involved in positive regulation of angiogenesis and transforming growth factor beta receptor signaling pathway. Acts upstream of or within several processes, including focal adhesion assembly; integrin-mediated signaling pathway; and substrate adhesion-dependent cell spreading. Located in focal adhesion and lamellipodium. Is expressed in several structures, including central nervous system; genitourinary system; immune system; inner ear; and lens. Orthologous to human PXN (paxillin). [provided by Alliance of Genome Resources, Dec 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.
