STRINGSTRING
PIM1 protein (Saccharomyces cerevisiae) - STRING interaction network
"PIM1" - ATP-dependent Lon protease, involved in degradation of misfolded proteins in mitochondria 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

PIM1ATP-dependent Lon protease, involved in degradation of misfolded proteins in mitochondria; required for biogenesis and maintenance of mitochondria; ATP-dependent serine protease that mediates the selective degradation of misfolded, unassembled or oxidatively damaged polypeptides as well as certain short-lived regulatory proteins in the mitochondrial matrix. May also have a chaperone function in the assembly of inner membrane protein complexes. Participates in the regulation of mitochondrial gene expression and in the maintenance of the integrity of the mitochondrial genome. Binds to mi [...] (1133 aa)    
Predicted Functional Partners:
MET5
Sulfite reductase beta subunit, involved in amino acid biosynthesis, transcription repressed by methionine; Catalyzes the reduction of sulfite to sulfide, one of several activities required for the biosynthesis of L-cysteine from sulfate (1442 aa)

RPT5
One of six ATPases of the 19S regulatory particle of the 26S proteasome involved in the degradation of ubiquitinated substrates; recruited to the GAL1-10 promoter region upon induction of transcription; similar to human TBP1; The 26S protease is involved in the ATP-dependent degradation of ubiquitinated proteins. The regulatory (or ATPase) complex confers ATP dependency and substrate specificity to the 26S complex (By similarity) (434 aa)

CTF8
Subunit of a complex with Ctf18p; shares some subunits with Replication Factor C; required for sister chromatid cohesion; Essential for the fidelity of chromosome transmission. Required for the DNA replication block checkpoint. Component of the RFC-like complex CTF18-RFC which is required for efficient establishment of chromosome cohesion during S-phase and may load or unload POL30/PCNA. During a clamp loading circle, the RFC-clamp complex binds to DNA and the recognition of the double- stranded/single-stranded junction stimulates ATP hydrolysis by RFC. The complex presumably provides [...] (133 aa)

PRE6
Alpha 4 subunit of the 20S proteasome; may replace alpha 3 subunit (Pre9p) under stress conditions to create a more active proteasomal isoform; GFP-fusion protein relocates from cytosol to the mitochondrial surface upon oxidative stress; The proteasome degrades poly-ubiquitinated proteins in the cytoplasm and in the nucleus. It is essential for the regulated turnover of proteins and for the removal of misfolded proteins. The proteasome is a multicatalytic proteinase complex that is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving [...] (254 aa)

SCL1
Alpha 1 subunit of the 20S proteasome involved in the degradation of ubiquitinated substrates; 20S proteasome is the core complex of the 26S proteasome; essential for growth; detected in the mitochondria; The proteasome degrades poly-ubiquitinated proteins in the cytoplasm and in the nucleus. It is essential for the regulated turnover of proteins and for the removal of misfolded proteins. The proteasome is a multicatalytic proteinase complex that is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basi [...] (252 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)

MCX1
Mitochondrial matrix protein; putative ATP-binding chaperone with non-proteolytic function; similar to bacterial ClpX proteins; ATP-dependent unfoldase that stimulates the incorporation of the pyridoxal phosphate cofactor into 5- aminolevulinate synthase (HEM1), thereby activating 5- aminolevulinate (ALA) synthesis, the first step in heme biosynthesis. Upregulates heme biosynthesis (520 aa)
