    Summary
    Predicted to enable several functions, including Hsp70 protein binding activity; enzyme binding activity; and modification-dependent protein binding activity. Predicted to be involved in several processes, including proteasomal protein catabolic process; protein folding; and regulation of protein metabolic process. Predicted to be located in several cellular components, including endoplasmic reticulum membrane; nuclear membrane; and perinuclear region of cytoplasm. Predicted to be part of proteasome complex. Predicted to be active in cytosol. Human ortholog(s) of this gene implicated in autosomal recessive distal hereditary motor neuronopathy 5. Orthologous to human DNAJB2 (DnaJ heat shock protein family (Hsp40) member B2). [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.
