STRINGSTRING
OMA1 protein (Saccharomyces cerevisiae) - STRING interaction network
"OMA1" - Metalloendopeptidase of the mitochondrial inner membrane, involved in turnover of membrane-embedded 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

OMA1Metalloendopeptidase of the mitochondrial inner membrane, involved in turnover of membrane-embedded proteins; member of a family of predicted membrane-bound metallopeptidases in prokaryotes and higher eukaryotes; Protease that is part of the quality control system in the inner membrane of mitochondria. Cleaves and thereby promotes the turnover of mistranslated or misfolded membrane proteins. Can cleave the misfolded multi-pass membrane protein OXA1 (345 aa)    
Predicted Functional Partners:
COA2
Cytochrome oxidase assembly factor; null mutation results in respiratory deficiency with specific loss of cytochrome oxidase activity; functions downstream of assembly factors Mss51p and Coa1p and interacts with assembly factor Shy1p; Required for efficient assembly of cytochrome c oxidase in the mitochondrial inner membrane. Seems to be involved in the SHY1-mediated step of cytochrome c oxidase maturation. May aid in stabilizing an early COX1 intermediate containing the nuclear subunits COX5A and COX6 (68 aa)

MGR3
Subunit of the mitochondrial (mt) i-AAA protease supercomplex, which degrades misfolded mitochondrial proteins; forms a subcomplex with Mgr1p that binds to substrates to facilitate proteolysis; required for growth of cells lacking mtDNA; Component of the mitochondrial inner membrane i-AAA protease supercomplex, which degrades misfolded mitochondrial proteins. Together with MGR1, functions in an adapter complex that targets substrates to the i-AAA protease for degradation. Required for growth of cells lacking the mitochondrial genome (501 aa)

MGR2
Protein required for growth of cells lacking the mitochondrial genome; Required for cell viability in cells lacking mitochondrial DNA (113 aa)

YME1
Catalytic subunit of the mitochondrial inner membrane i-AAA protease complex, which is responsible for degradation of unfolded or misfolded mitochondrial gene products; mutation causes an elevated rate of mitochondrial turnover; Catalytic subunit of the mitochondrial inner membrane i- AAA protease supercomplex required for mitochondrial inner membrane protein turnover. The protease is probably ATP-dependent. Important to maintain the integrity of the mitochondrial compartment. Required both for the degradation of unassembled subunit 2 of cytochrome c oxidase (COX2) and for efficient as [...] (747 aa)

AFG3
Component, with Yta12p, of the mitochondrial inner membrane m-AAA protease that mediates degradation of misfolded or unassembled proteins and is also required for correct assembly of mitochondrial enzyme complexes; Acts as a component of the m-AAA protease complex which is a ATP-dependent metalloprotease mediating degradation of non- assembled mitochondrial inner membrane proteins. The complex is necessary for the assembly of mitochondrial respiratory chain and ATPase complexes. Function both in post-translational assembly and in the turnover of mistranslated or misfolded polypeptides (761 aa)

SHY1
Mitochondrial inner membrane protein required for assembly of cytochrome c oxidase (complex IV); associates with complex IV assembly intermediates and complex III/complex IV supercomplexes; similar to human SURF1 involved in Leigh Syndrome; Required for efficient assembly of cytochrome c oxidase in the mitochondrial inner membrane. Involved in a step that couples MSS51-COX14-dependent regulation of COX1 translation to early steps of cytochrome c oxidase assembly (389 aa)

GLY1
Threonine aldolase, catalyzes the cleavage of L-allo-threonine and L-threonine to glycine; involved in glycine biosynthesis; Catalyzes the cleavage of L-allo-threonine and L- threonine to glycine and acetaldehyde (387 aa)
       
      0.709
VMS1
Component of a Cdc48p-complex involved in protein quality control; exhibits cytosolic and ER-membrane localization, with Cdc48p, during normal growth, and contributes to ER-associated degradation (ERAD) of specific substrates at a step after their u /.../ination; forms a mitochondrially-associated complex with Cdc48p and Npl4p under oxidative stress that is required for ubiquitin-mediated mitochondria-associated protein degradation (MAD); conserved in C. elegans and humans; Involved in the endoplasmic reticulum (ER)-associated degradation (ERAD) pathway. Component of an evolutionarily [...] (632 aa)

YTA12
Component, with Afg3p, of the mitochondrial inner membrane m-AAA protease that mediates degradation of misfolded or unassembled proteins and is also required for correct assembly of mitochondrial enzyme complexes; Acts as a component of the m-AAA protease complex which is a ATP-dependent metalloprotease mediating degradation of non- assembled mitochondrial inner membrane proteins. The complex is necessary for the assembly of mitochondrial respiratory chain and ATPase complexes. Function both in post-translational assembly and in the turnover of mistranslated or misfolded polypeptides (825 aa)

POR1
Mitochondrial porin (voltage-dependent anion channel), outer membrane protein required for the maintenance of mitochondrial osmotic stability and mitochondrial membrane permeability; phosphorylated; Forms a channel through the cell membrane that allows diffusion of small hydrophilic molecules. The channel adopts an open conformation at low or zero membrane potential and a closed conformation at potentials above 30-40 mV. The open state has a weak anion selectivity whereas the closed state is cation- selective. Is the major permeability factor of the mitochondrial outer membrane (283 aa)
