CC -!- FUNCTION: Component of E3 ubiquitin ligase SCF complexes, which mediate
CC the ubiquitination and subsequent proteasomal degradation of target
CC proteins. Seems to recruit the E2 ubiquitination enzyme, like
CC UBC3/CDC34, to the complex and brings it into close proximity to the
CC substrate. Component of the rik1-associated E3 ubiquitin ligase complex
CC that shows ubiquitin ligase activity and is required for histone H3K9
CC methylation. H3K9me represents a specific tag for epigenetic
CC transcriptional repression by recruiting swi6/HP1 to methylated
CC histones which leads to transcriptional silencing within centromeric
CC heterochromatin, telomeric regions and at the silent mating-type loci.
CC {ECO:0000269|PubMed:12167173}.
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC -!- SUBUNIT: Part of a SCF E3 ubiquitin ligase complex containing psh1,
CC pip1, pcul1 and the F-box proteins pop1 and pop2. Instead of the
CC pop1/pop2 heterodimer also homooligomers of pop1 or pop2 may be present
CC in the complex. Component of the rik1-associated E3 ubiquitin ligase
CC complex composed of at least clr4, cul4, pip1, raf1 and raf2. Interacts
CC with cul3. {ECO:0000269|PubMed:12167173, ECO:0000269|PubMed:14527422,
CC ECO:0000269|PubMed:16024659}.
CC -!- INTERACTION:
CC O13959; Q9Y709: skp1; NbExp=6; IntAct=EBI-1112060, EBI-1172248;
CC -!- SUBCELLULAR LOCATION: Cytoplasm. Nucleus.
CC -!- DOMAIN: The RING-type zinc finger domain is essential for ubiquitin
CC ligase activity. It coordinates an additional third zinc ion.
