    Summary
    Predicted to enable signaling receptor binding activity. Involved in cell-cell adhesion and hemidesmosome assembly. Located in adherens junction and hemidesmosome. Part of laminin-3 complex. Human ortholog(s) of this gene implicated in junctional epidermolysis bullosa and lung small cell carcinoma. Orthologous to human LAMA3 (laminin 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.
