    Summary
    Predicted to enable actin filament binding activity. Acts upstream of or within cardiac muscle cell development; in utero embryonic development; and vasculogenesis. Located in Z disc. Part of filamentous actin. Is expressed in several structures, including diaphragm; heart; and musculature. Human ortholog(s) of this gene implicated in Klippel-Feil syndrome 4. Orthologous to human MYO18B (myosin XVIIIB). [provided by Alliance of Genome Resources, Nov 2024]

    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.
