STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

raf2Rik1-associated factor 2; 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. Has a role in both mitotic and meiotic chromosome segregation. (636 aa)    
Predicted Functional Partners:
cul4
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 [...]

clr4
Histone-lysine N-methyltransferase, H3 lysine-9 specific; Histone methyltransferase. Catalytic 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. Belongs to the class V-like SAM-binding methyltransferase superfamily. Histone-lysine methyltransfer [...]

rik1
Chromatin modification-related protein rik1; 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. Rik1 has also a function in meiotic telomere clustering.

rbx1
RING-box protein pip1; 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 s [...]

ddb1
DNA damage-binding protein 1; Component of an E3 ubiquitin-protein ligase that includes cul4 (By similarity). Required for ubiquitination and the subsequent degradation of the DNA replication licensing factor cdt1 and of the ribonucleotide reductase inhibitor spd1. Also required for transcription-coupled nucleotide excision repair.

stc1
Meiotic chromosome segregation protein P8B7.28c; Required for meiotic chromosome segregation.

mms19
DNA repair/transcription protein mms19; Key component of the cytosolic iron-sulfur protein assembly (CIA) machinery that mediates the incorporation of iron-sulfur cluster into apoproteins specifically involved in DNA metabolism and genomic integrity. Acts as an adapter between early-acting CIA components and a subset of cellular target iron-sulfur proteins such as rad3/xpd and dna2, thereby playing a key role in nucleotide excision repair (NER) and RNA polymerase II (POL II) transcription (By similarity).

cut23
Anaphase-promoting complex subunit 8; Component of the anaphase-promoting complex/cyclosome (APC/C), a cell cycle-regulated E3 ubiquitin-protein ligase complex that controls progression through mitosis and the G1 phase of the cell cycle. The APC/C is thought to confer substrate specificity and, in the presence of ubiquitin-conjugating E2 enzymes, it catalyzes the formation of protein-ubiquitin conjugates that are subsequently degraded by the 26S proteasome. Has a role in promoting metaphase to anaphase transition via the ubiquitination of specific mitotic substrates.

cul1
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.
