STRINGSTRING
DEF1 protein (Saccharomyces cerevisiae) - STRING interaction network
"DEF1" - RNAPII degradation factor, forms a complex with Rad26p in chromatin, enables ubiquitination and proteolysis of RNAPII present in an elongation complex in Saccharomyces cerevisiae
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

DEF1RNAPII degradation factor, forms a complex with Rad26p in chromatin, enables ubiquitination and proteolysis of RNAPII present in an elongation complex; mutant is deficient in Zip1p loading onto chromosomes during meiosis; RNA polymerase II degradation factor recruits the ubiquitination machinery to the RNA polymerase II for polyubiquitination, removal and degradation, when RAD26 fails to efficiently displace stalled RNA polymerase II. Also involved in telomere length regulation (738 aa)    
Predicted Functional Partners:
RAD26
Protein involved in transcription-coupled nucleotide excision repair of UV-induced DNA lesions; recruitment to DNA lesions is dependent on an elongating RNA polymerase II; homolog of human CSB protein; May be involved in the preferential repair of active genes (1085 aa)

RPO21
RNA polymerase II largest subunit B220, part of central core; phosphorylation of C-terminal heptapeptide repeat domain regulates association with transcription and splicing factors; similar to bacterial beta-prime; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Largest and catalytic component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Forms the polymerase active center together with the second largest subunit. Pol II is the central component of the basal [...] (1733 aa)

RAD7
Protein that recognizes and binds damaged DNA in an ATP-dependent manner (with Rad16p) during nucleotide excision repair; subunit of Nucleotide Excision Repair Factor 4 (NEF4) and the Elongin-Cullin-Socs (ECS) ligase complex; Component of the global genome repair (GGR) complex which promotes global genome nucleotide excision repair (GG-NER) which removes DNA damage from nontranscribing DNA. This protein is one of 10 proteins (RAD1, 2,3,4,7,10,14, 16,23 and MMS19) involved in excision repair of DNA damaged with UV light, bulky adducts, or cross-linking agents (565 aa)

DCP2
Catalytic subunit of the Dcp1p-Dcp2p decapping enzyme complex, which removes the 5’ cap structure from mRNAs prior to their degradation; member of the Nudix hydrolase family; Catalytic component of the decapping complex necessary for the degradation of mRNAs, both in normal mRNA turnover and in nonsense-mediated mRNA decay (PubMed-10508173, PubMed-11139489, PubMed-11741542). Removes the 7-methyl guanine cap structure from mRNA molecules, yielding a 5’-phosphorylated mRNA fragment and 7m- GDP (PubMed-12554866). Decapping is the major pathway of mRNA degradation in yeast and occurs throu [...] (970 aa)

MPT5
Member of the Puf family of RNA-binding proteins; binds to mRNAs encoding chromatin modifiers and spindle pole body components; involved in longevity, maintenance of cell wall integrity, and sensitivity to and recovery from pheromone arrest; RNA-binding protein involved in post-transcriptional regulation. Negatively regulates expression of HO by binding to the 3’-UTR of HO mRNA. Predominantly binds to mRNAs encoding chromatin modifiers and spindle pole body components. Recognizes and binds to 5’-TGTAA[CT]A[AT]TA-3’ in the 3’-UTR of target mRNAs. Multicopy suppressor of POP2 mutation. R [...] (859 aa)

ELC1
Elongin C, conserved among eukaryotes; forms a complex with Cul3p that polyubiquitylates monoubiquitylated RNA polymerase II to trigger its proteolysis; plays a role in global genomic repair; Prevents degradation of interacting proteins like PCL6 by the proteasome (99 aa)

RAD16
Protein that recognizes and binds damaged DNA in an ATP-dependent manner (with Rad7p) during nucleotide excision repair; subunit of Nucleotide Excision Repair Factor 4 (NEF4) and the Elongin-Cullin-Socs (ECS) ligase complex; Component of the global genome repair (GGR) complex which promotes global genome nucleotide excision repair (GG-NER) which removes DNA damage from nontranscribing DNA. Involved in differential repair of DNA after UV damage. Will repair preferentially the MAT-alpha locus compared with the HML-alpha locus (790 aa)

ELA1
Elongin A; F-box protein that forms a heterodimer with Elc1p and is required for ubiquitin-dependent degradation of the RNA Polymerase II subunit Rpo21p; subunit of the Elongin-Cullin-Socs (ECS) ligase complex (379 aa)

PEP1
Type I transmembrane sorting receptor for multiple vacuolar hydrolases; cycles between the late-Golgi and prevacuolar endosome-like compartments; Functions as a sorting receptor in the Golgi compartment required for the intracellular sorting and delivery of soluble vacuolar proteins, like carboxypeptidase Y (CPY) and proteinase A. May execute multiple rounds of sorting by cycling between the late Golgi and a prevacuolar endosome-like compartment.
