    Summary
    Enables integrin binding activity. Involved in several processes, including integrin-mediated signaling pathway; positive regulation of ERK1 and ERK2 cascade; and positive regulation of macrophage cytokine production. Acts upstream of or within nervous system development; positive regulation of axon extension; and positive regulation of protein phosphorylation. Located in external side of plasma membrane. Is active in GABA-ergic synapse and presynapse. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; heart; and sensory organ. Human ortholog(s) of this gene implicated in progressive familial intrahepatic cholestasis. Orthologous to human SEMA7A (semaphorin 7A (JohnMiltonHagen blood group)).

    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.
