SKP1 component, dimerisation (IPR016072)

Short name: Skp1_comp_dimer

Overlapping homologous superfamilies

Domain relationships



SKP1 (together with SKP2) was identified as an essential component of the cyclin A-CDK2 S phase kinase complex [PMID: 10205047]. It was found to bind several F-box containing proteins (e.g., Cdc4, Skp2, cyclin F) and to be involved in the ubiquitin protein degradation pathway. A yeast homologue of SKP1 (P52286) was identified in the centromere bound kinetochore complex [PMID: 8670864] and is also involved in the ubiquitin pathway [PMID: 9390558]. In Dictyostelium discoideum (Slime mold) FP21 was shown to be glycosylated in the cytosol and has homology to SKP1 [PMID: 7852383].

This entry represents a dimerisation domain found at the C-terminal of SKP1 proteins [PMID: 11099048], as well as in subunit D of the centromere DNA-binding protein complex Cbf3 [PMID: 12553912]. This domain is multi-helical in structure, and consists of an interlocked herterodimer in F-box proteins.
