    Summary
    Enables heparin binding activity and hyaluronic acid binding activity. Acts upstream of or within extracellular matrix organization; protein localization; and retina morphogenesis in camera-type eye. Located in interphotoreceptor matrix. Is expressed in embryo; retina inner nuclear layer; retina nuclear layer; and retina outer nuclear layer. Used to study retinitis pigmentosa 56 and vitelliform macular dystrophy. Human ortholog(s) of this gene implicated in retinitis pigmentosa 56 and vitelliform macular dystrophy. Orthologous to human IMPG2 (interphotoreceptor matrix proteoglycan 2).

    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.
