Summary: Enables several functions, including fibronectin binding activity; integrin binding activity; and laminin binding activity. Involved in several processes, including maternal process involved in female pregnancy; positive regulation of epithelial cell migration; and regulation of cell projection organization. Located in cell surface; growth cone filopodium; and perinuclear region of cytoplasm. Part of integrin alpha3-beta1 complex. Is active in glutamatergic synapse and postsynaptic membrane. Biomarker of glomerulonephritis and myocardial infarction. Human ortholog(s) of this gene implicated in junctional epidermolysis bullosa. Orthologous to human ITGA3 (integrin subunit alpha 3).

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.
