    Summary
    Predicted to enable oxygen binding activity. Acts upstream of or within several processes, including brown fat cell differentiation; enucleate erythrocyte differentiation; and response to hypoxia. Is expressed in brown fat; heart; skeletal muscle; and somite. Human ortholog(s) of this gene implicated in acute kidney failure. Orthologous to human MB (myoglobin).

    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.
