STRINGSTRING
MPT5 protein (Saccharomyces cerevisiae) - STRING interaction network
"MPT5" - Member of the Puf family of RNA-binding proteins 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

MPT5Member 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)    
Predicted Functional Partners:
POP2
RNase of the DEDD superfamily, subunit of the Ccr4-Not complex that mediates 3’ to 5’ mRNA deadenylation; Acts as probably catalytic component of the CCR4-NOT core complex, which in the nucleus seems to be a general transcription factor, and in the cytoplasm the major mRNA deadenylase involved in mRNA turnover. In vitro, POP2 has 3’- exoribonuclease activity with a preference for poly(A) RNAs, but also degrades poly(U) and poly(C) RNAs. Is part of a glucose- sensing system involved in growth control in response to glucose availability (433 aa)

SST2
GTPase-activating protein for Gpa1p, regulates desensitization to alpha factor pheromone; also required to prevent receptor-independent signaling of the mating pathway; member of the RGS (regulator of G-protein signaling) family; Desensitization to alpha-factor pheromone. Is involved in regulating the signaling pathway for responding to mating pheromone (698 aa)

DHH1
Cytoplasmic DExD/H-box helicase, stimulates mRNA decapping; coordinates distinct steps in mRNA function and decay, interacts with both the decapping and deadenylase complexes, may have a role in mRNA export and translation; C-terminus of Dhh1p inter /.../ith Ngr1p and promotes POR1, but not EDC1 mRNA decay; ATP-dependent RNA helicase involved in mRNA turnover, and more specifically in mRNA decapping by activating the decapping enzyme DCP1 (PubMed-11780629, PubMed-12032091, PubMed-11696541, PubMed-12730603, PubMed-15703442.

CDC28
Catalytic subunit of the main cell cycle cyclin-dependent kinase (CDK); alternately associates with G1 cyclins (CLNs) and G2/M cyclins (CLBs) which direct the CDK to specific substrates; This protein is essential for the completion of the start, the controlling event, in the cell cycle. More than 200 substrates have been identified (298 aa)

CCR4
Component of the CCR4-NOT transcriptional complex, which is involved in regulation of gene expression; component of the major cytoplasmic deadenylase, which is involved in mRNA poly(A) tail shortening; Acts as catalytic component of the CCR4-NOT core complex, which in the nucleus seems to be a general transcription factor, and in the cytoplasm the major mRNA deadenylase involved in mRNA turnover. CCR4 has 3’-5’ RNase activity with a strong preference for polyadenylated substrates and also low exonuclease activity towards single-stranded DNA. Discovered because of its role in the contro [...] (837 aa)

KSS1
Mitogen-activated protein kinase (MAPK) involved in signal transduction pathways that control filamentous growth and pheromone response; the KSS1 gene is nonfunctional in S288C strains and functional in W303 strains; Together with closely related FUS3, KSS1 is the final kinase in the signal transduction cascade regulating activation/repression of the mating and filamentation pathways, induced by pheromone and nitrogen/carbon limitation, respectively. Phosphorylated KSS1 activates both pathways, whereas activated FUS3 activates the mating but suppresses the filamentation pathway. KSS1 a [...] (368 aa)

FUS3
Mitogen-activated serine/threonine protein kinase involved in mating; phosphoactivated by Ste7p; substrates include Ste12p, Far1p, Bni1p, Sst2p; inhibits invasive growth during mating by phosphorylating Tec1p, promoting its degradation; Together with closely related KSS1, FUS3 is the final kinase in the signal transduction cascade regulating activation/repression of the mating and filamentation pathways, induced by pheromone and nitrogen/carbon limitation, respectively.

DEF1
RNAPII 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.
