Summary
Enables identical protein binding activity and small GTPase binding activity. Contributes to ubiquitin-protein transferase activity. Involved in several processes, including negative regulation of Rho protein signal transduction; proteasome-mediated ubiquitin-dependent protein catabolic process; and stress fiber assembly. Located in nuclear body. Part of Cul3-RING ubiquitin ligase complex. [provided by Alliance of Genome Resources, Jul 2025]

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.

RNA

  1. NR_110933.2 RNA Sequence

    Status: VALIDATED

    Description
    Transcript Variant: This variant (2) uses alternate splice sites in two internal exons, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
