Data (including data from studies using knockout mice and cultured cells from knockout mice) suggest that HACD1 and HACD2 exhibit overlapping substrate specificities and thus appear to represent redundant activities in skeletal muscle.

    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.
