Gene

pip1

Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Status

Functioni

Component of E3 ubiquitin ligase SCF complexes, which mediate the ubiquitination and subsequent proteasomal degradation of target proteins. Seems to recruit the E2 ubiquitination enzyme, like UBC3/CDC34, to the complex and brings it into close proximity to the substrate. 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 heterochromatin, telomeric regions and at the silent mating-type loci.1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
