STRINGSTRING
MDM31 protein (Saccharomyces cerevisiae) - STRING interaction network
"MDM31" - Mitochondrial inner membrane protein with similarity to Mdm32p, required for normal mitochondrial morphology and inheritance 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

MDM31Mitochondrial inner membrane protein with similarity to Mdm32p, required for normal mitochondrial morphology and inheritance; interacts genetically with MMM1, MDM10, MDM12, and MDM34; Involved in the organization of the mitochondrial membranes and the global structure of the mitochondria. Also required for mitochondrial distribution and mobility as well as for the maintenance of mitochondrial DNA nucleoids structures (579 aa)    
Predicted Functional Partners:
MMM1
ER integral membrane protein, component of the ERMES complex that links the ER to mitochondria and may promote inter-organellar calcium and phospholipid exchange as well as coordinating mitochondrial DNA replication and growth; Component of the ERMES/MDM complex, which serves as a molecular tether to connect the endoplasmic reticulum and mitochondria. Components of this complex are involved in the control of mitochondrial shape and protein biogenesis and may function in phospholipid exchange. The MDM12-MMM1 subcomplex functions in the major beta-barrel assembly pathway that is responsi [...] (426 aa)

MDM12
Mitochondrial outer membrane protein, required for transmission of mitochondria to daughter cells; component of the ERMES complex that links the ER to mitochondria; may influence import and assembly of outer membrane beta-barrel proteins; Component of the ERMES/MDM complex, which serves as a molecular tether to connect the endoplasmic reticulum and mitochondria.

MDM10
Subunit of both the ERMES complex that links the ER to mitochondria, and of the mitochondrial sorting and assembly machinery (SAM complex) that functions in import and assembly of outer membrane beta-barrel proteins; Component of the ERMES/MDM complex, which serves as a molecular tether to connect the endoplasmic reticulum and mitochondria. Components of this complex are involved in the control of mitochondrial shape and protein biogenesis and may function in phospholipid exchange.

SHE9
Mitochondrial inner membrane protein required for normal mitochondrial morphology, may be involved in fission of the inner membrane; forms a homo-oligomeric complex; Required for the maintenance of the structure of the mitochondrial inner membrane. Involved in mitochondrial morphology. Causes growth arrest when highly overexpressed (456 aa)

MDM35
Mitochondrial intermembrane space protein; mutation affects mitochondrial distribution and morphology; contains twin cysteine-x9-cysteine motifs; Involved in mitochondrial distribution and morphology. Mediates the import of UPS1, UPS2 and UPS3, 3 atypical mitochondrial intermembrane space (IMS) proteins lacking the two major IMS-targeting signals, into the intermembrane space. The UPS1-MDM35 complex mediates the transfer of phosphatidic acid (PA) between liposomes and probably functions as a PA transporter across the mitochondrion intermembrane space (PubMed-26071602, PubMed-26071601, [...] (86 aa)

UPS1
Mitochondrial intermembrane space protein that regulates mitochondrial cardiolipin levels, null has defects in Mgm1p processing, integrity of mitochondrial inner membrane complexes, and mitochondrial morphology; ortholog of human PRELI; Required for maintenance of normal mitochondrial morphology (PubMed-16754953, PubMed-26071601). Required for PCP1- dependent processing of MGM1 (PubMed-16754953).

GPA1
GTP-binding alpha subunit of the heterotrimeric G protein that couples to pheromone receptors; negatively regulates the mating pathway by sequestering G(beta)gamma and by triggering an adaptive response; activates Vps34p at the endosome; Alpha subunit of the heterotrimeric guanine nucleotide- binding protein (G protein) that mediates mating pheromone signal transduction. Binding of alpha-factor or a-factor to its cognate transmembrane receptor STE2 and STE3, respectively, allows the receptor to serve as a guanine nucleotide exchange factor (GEF) on GPA1. The exchange of GDP for GTP on [...] (472 aa)

UGO1
Outer membrane component of the mitochondrial fusion machinery; binds directly to Fzo1p and Mgm1p and thus links these two GTPases during mitochondrial fusion; involved in fusion of both the outer and inner membranes; facilitates dimerization of Fzo /.../ing fusion; import into the outer membrane is mediated by Tom70p and Mim1p; has similarity to carrier proteins but is not likely to function as a transmembrane transporter; Required for mitochondrial fusion as well as normal mitochondrial morphology by bridging the essential interaction between FZO1 and MGM1.
