STRINGSTRING
MGR3 protein (Saccharomyces cerevisiae) - STRING interaction network
"MGR3" - Subunit of the mitochondrial 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

MGR3Subunit 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)    
Predicted Functional Partners:
MGR1
Subunit of the mitochondrial (mt) i-AAA protease supercomplex, which degrades misfolded mitochondrial proteins; forms a subcomplex with Mgr3p that binds to substrates to facilitate proteolysis; required for growth of cells lacking mtDNA; Component of the mitochondrial inner membrane i-AAA protease supercomplex required for mitochondrial inner membrane protein turnover. Together with MGR3, functions in an adapter complex that targets substrates to the i-AAA protease for degradation. Required for growth of cells lacking the mitochondrial genome (417 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)

OMA1
Metalloendopeptidase 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)

TAZ1
Lyso-phosphatidylcholine acyltransferase, required for normal phospholipid content of mitochondrial membranes; may remodel acyl groups of cardiolipin in the inner membrane; human ortholog tafazzin is implicated in Barth syndrome; Acyltransferase which mediates the conversion of 1-acyl- sn-glycero-3-phosphocholine (LPC) into phosphatidylcholine (PC). Displays a broad LPC fatty acyl chain substrate specificity utilizing LPC molecules ranging in length from C-10 to C-20. Does not utilize other lysolipids than LPC as acceptor. Also shows acyl-CoA-independent acyltransferase activity. Requi [...] (381 aa)

COX18
Mitochondrial integral inner membrane protein required for membrane insertion of C-terminus of Cox2p; interacts genetically and physically with Mss2p and Pnt1p; similar to S. cerevisiae Oxa1, N. crassa Oxa2p, and E. coli YidC; Required for the insertion of integral membrane proteins into the mitochondrial inner membrane. Essential for the activity and assembly of cytochrome c oxidase. Plays a central role in the translocation and export of the C-terminal part of the COX2 protein into the mitochondrial intermembrane space (316 aa)
       
 
  0.810
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)

COX20
Mitochondrial inner membrane protein, required for proteolytic processing of Cox2p and its assembly into cytochrome c oxidase; Involved in the assembly of the cytochrome oxidase complex.
