STRINGSTRING
MGR1 protein (Saccharomyces cerevisiae) - STRING interaction network
"MGR1" - 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

MGR1Subunit 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)    
Predicted Functional Partners:
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)

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)
       
 
  0.845
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. Required for the maturation and subsequent assembly of the mitochondrially encoded COX2, the precursor of subunit 2 of cytochrome oxidase (205 aa)
       
 
  0.837
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)

NPL6
Component of the RSC chromatin remodeling complex; interacts with Rsc3p, Rsc30p, Ldb7p, and Htl1p to form a module important for a broad range of RSC functions; Component of the chromatin structure remodeling complex (RSC), which is involved in transcription regulation and nucleosome positioning. RSC is responsible for the transfer of a histone octamer from a nucleosome core particle to naked DNA. The reaction requires ATP and involves an activated RSC-nucleosome intermediate. Remodeling reaction also involves DNA translocation, DNA twist and conformational change. As a reconfigurer of [...] (435 aa)
