Summary: Predicted to enable several functions, including cullin family protein binding activity; ubiquitin protein ligase binding activity; and ubiquitin-like protein ligase activity. Predicted to contribute to ubiquitin-protein transferase activity. Involved in several processes, including SCF-dependent proteasomal ubiquitin-dependent protein catabolic process; cellular response to UV; and protein ubiquitination. Acts upstream of or within protein K48-linked ubiquitination; protein catabolic process; and protein monoubiquitination. Located in cytosol. Part of Cul4A-RING E3 ubiquitin ligase complex and SCF ubiquitin ligase complex. Is expressed in several structures, including genitourinary system. Orthologous to human RBX1 (ring-box 1).

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.
