    Summary
    Enables integrin binding activity involved in cell-matrix adhesion. Acts upstream of or within neutrophil chemotaxis. Located in basal plasma membrane. Part of integrin alpha9-beta1 complex. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and skin. Used to study congenital chylothorax. Human ortholog(s) of this gene implicated in cerebral infarction; hypertension; and pancreatic cancer. Orthologous to human ITGA9 (integrin subunit alpha 9).

    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.
