STRINGSTRING
MPS3 protein (Saccharomyces cerevisiae) - STRING interaction network
"MPS3" - Nuclear envelope protein required for SPB duplication and nuclear fusion 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

MPS3Nuclear envelope protein required for SPB duplication and nuclear fusion; localizes to the SPB half bridge and at telomeres during meiosis; required with Ndj1p and Csm4p for meiotic bouquet formation and telomere-led rapid prophase movement; Required for the first step of spindle pole body duplication in G1. Essential for nuclear division and fusion. Functions in sister chromatid cohesion establishment. Connects the spindle pole body with the nuclear envelope through its interaction with MPS2 and mediates meiotic bouquet formation and rapid chromosome movements in meiotic prophase. Fun [...] (682 aa)    
Predicted Functional Partners:
CSM4
Protein required for accurate chromosome segregation during meiosis; involved in meiotic telomere clustering (bouquet formation) and telomere-led rapid prophase movements; Involved in chromosome segregation during meiosis. Involved in meiotic telomere clustering (bouquet formation) and telomere-led rapid prophase movements (156 aa)

NDJ1
Meiosis-specific telomere protein, required for bouquet formation, effective homolog pairing, ordered cross-over distribution, sister chromatid cohesion at meiotic telomeres, chromosomal segregation and telomere-led rapid prophase movement; Required for telomeric clustering (bouquet stage) during meiosis 1 prophase, formation and efficient homolog pairing, meiosis 1 disjunction, and telomere deletion during meiosis. Promotes also meiotic recombination (352 aa)

MPS2
Essential membrane protein localized at the nuclear envelope and spindle pole body (SPB), required for insertion of the newly duplicated SPB into the nuclear envelope; potentially phosphorylated by Cdc28p; Component of the spindle pole body (SPB) required for insertion of the nascent SPB into the nuclear envelope and for the proper execution of spindle pole body (SPB) duplication (387 aa)
     
 
  0.927
CDC31
Calcium-binding component of the spindle pole body (SPB) half-bridge, required for SPB duplication in mitosis and meiosis II; homolog of mammalian centrin; binds multiubiquitinated proteins and is involved in proteasomal protein degradation; Functions as a component of the nuclear pore complex (NPC) and the spindle pole body (SPB) half-bridge. At the SPB, it is recruited by KAR1 and MPS3 to the SPB half-bridge and involved in the initial steps of SPB duplication. It probably plays a similar role in de novo assembly of NPCs at the nuclear envelope. Also involved in connection with the p [...] (161 aa)

ECO1
Acetyltransferase required for establishment of sister chromatid cohesion; modifies Smc3p at replication forks and Mcd1p in response to ds DNA breaks; has a C2H2-type zinc finger; mutations in human homolog ESCO2 cause Roberts syndrome; Required for establishment of sister chromatid cohesion during S phase but not for its further maintenance during G2 or M phases or for loading the cohesin complex onto DNA. Interacts with the three known alternate replication factor C (RFC) complexes, suggesting that these complexes have essential but redundant activity in cohesion establishment. Acts [...] (281 aa)

SIR4
Silent information regulator that, together with SIR2 and SIR3, is involved in assembly of silent chromatin domains at telomeres and the silent mating-type loci; potentially phosphorylated by Cdc28p; some alleles of SIR4 prolong lifespan; The proteins SIR1 through SIR4 are required for transcriptional repression of the silent mating type loci, HML and HMR. The proteins SIR2 through SIR4 repress mulitple loci by modulating chromatin structure. Involves the compaction of chromatin fiber into a more condensed form (1358 aa)
       
 
  0.824
NDC1
Nuclear envelope protein with multiple putative transmembrane domains, required for nuclear pore complex assembly and spindle pole body duplication; required for meiosis II; Functions as a component of the nuclear pore complex (NPC) and the spindle pole body (SPB), probably by playing a key role in de novo assembly and insertion of both structures in the nuclear envelope. In SPB duplication NDC1 is required for the insertion of the cytoplasmic side of the SPB in the nuclear envelope, thus allowing for the assembly of the nucleoplasmic SPB side. NPC components, collectively referred to [...] (655 aa)
