STRINGSTRING
SOM1 protein (Saccharomyces cerevisiae) - STRING interaction network
"SOM1" - Subunit of the mitochondrial inner membrane peptidase, which is required for maturation of mitochondrial proteins of the intermembrane space 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

SOM1Subunit of the mitochondrial inner membrane peptidase, which is required for maturation of mitochondrial proteins of the intermembrane space; Som1p facilitates cleavage of a subset of substrates; contains twin cysteine-x9-cysteine motifs; Non-catalytic component of the mitochondrial inner membrane peptidase (IMP) complex. IMP catalyzes the removal of signal peptides required for the targeting of proteins from the mitochondrial matrix, across the inner membrane, into the inter- membrane space. SOM1 facilitates cleavage of a subset of IMP substrates (74 aa)    
Predicted Functional Partners:
IMP1
Catalytic subunit of the mitochondrial inner membrane peptidase complex, required for maturation of mitochondrial proteins of the intermembrane space; complex contains Imp1p and Imp2p (both catalytic subunits), and Som1p; Catalytic component of the mitochondrial inner membrane peptidase (IMP) complex. IMP catalyzes the removal of signal peptides required for the targeting of proteins from the mitochondrial matrix, across the inner membrane, into the inter- membrane space. The two catalytic IMP subunits seem to have non- overlapping substrate specificities. IMP1 substrates include nucle [...] (190 aa)

PNT1
Mitochondrial integral inner membrane protein involved in membrane insertion of C-terminus of Cox2p, interacts genetically and physically with Cox18p; deletion mutant sensitive to the anti-Pneumocystis carinii drug pentamidine; Probably involved in mitochondrial export. Confers resistance to the anti-pneumocystis carinii drug pentamidine. May act by the removal of pentamidine, or its damage targets, from the matrix by an active-transport mechanism (423 aa)

MSS2
Peripherally bound inner membrane protein of the mitochondrial matrix involved in membrane insertion of C-terminus of Cox2p, interacts genetically and physically with Cox18p; Required to stabilize mitochondrial cytochrome C oxidase subunit 2 (COX2) and to translocate the C-terminal domain of COX2 through the inner membrane (351 aa)
           
  0.680
PET111
Mitochondrial translational activator specific for the COX2 mRNA; located in the mitochondrial inner membrane; Required for translation of the mitochondrial gene for cytochrome c oxidase subunit II (COX2) (800 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)

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)
