    Summary
    Enables ubiquitin-like ligase-substrate adaptor activity. Involved in DNA damage response and protein K63-linked ubiquitination. Part of SCF ubiquitin ligase complex. Is active in site of double-strand break. Is expressed in cerebellum; cerebral cortex; liver; and spleen. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease type 2B2; ataxia-oculomotor apraxia type 4; and microcephaly, seizures, and developmental delay. Orthologous to human PNKP (polynucleotide kinase 3'-phosphatase). [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.
