Summary
Enables ubiquitin-like ligase-substrate adaptor activity. Involved in positive regulation of double-strand break repair via homologous recombination and protein K63-linked ubiquitination. Acts upstream of or within several processes, including mitotic cell cycle phase transition; positive regulation of intracellular estrogen receptor signaling pathway; and positive regulation of protein polyubiquitination. Part of SCF ubiquitin ligase complex. Is expressed in several structures, including blastocyst; brain; compacted morula; and retina nuclear layer. Human ortholog(s) of this gene implicated in prostate carcinoma. Orthologous to human SKP2 (S-phase kinase associated protein 2). [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.
