Cullin-1; Core component of multiple cullin-RING-based SCF (SKP1-CUL1- F-box protein) E3 ubiquitin-protein ligase complexes, which mediate the ubiquitination of target proteins. The functional specificity of the SCF complex depends on the F-box protein as substrate recognition component. SCF(pop1-pop2) is required for the maintenance of ploidy and directs ubiquitination of cig2; Belongs to the cullin family.

Cullin-3; Probable core component of multiple cullin-RING-based BC3B (BTB-CUL3-BTB) E3 ubiquitin-protein ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of target proteins. As a scaffold protein may contribute to catalysis through positioning of the substrate and the ubiquitin-conjugating enzyme. The functional specificity of the BC3B complex depends on the substrate recognition component (By similarity). Involved in ubiquitin-mediated degradation of btb3.

SCF(pop1-pop2) is required for the maintenance of ploidy and directs ubiquitination of cig2; Belongs to the cullin family.

Cullin-4; Required, indirectly, for activation of ribonucleotide reductase through the degradation of the protein spd1, thereby supplying deoxyribonucleotides for DNA replication and repair. Also has a role as a scaffold for assembling ubiquitin ligases. Component of the rik1-associated E3 ubiquitin ligase complex that shows ubiquitin ligase activity and is required for histone H3K9 methylation. H3K9me represents a specific tag for epigenetic transcriptional repression by recruiting swi6/HP1 to methylated histones which leads to transcriptional silencing within centromeric heterochroma [...]
