STRINGSTRING
CSN9 protein (Saccharomyces cerevisiae) - STRING interaction network
"CSN9" - Subunit of the Cop9 signalosome, which is required for deneddylation, or removal of the ubiquitin-like protein Rub1p from Cdc53p 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

YIH1
Protein that inhibits activation of Gcn2p, an eIF2 alpha subunit protein kinase, by competing for Gcn1p binding, thus impacting gene expression in response to starvation; has sequence and functional similarity to the mouse IMPACT gene; Translational regulator that ensures constant high levels of translation under amino acid starvation. Plays a role as a negative regulator of the GCN2 kinase activity; impairs GCN1- mediated GCN2 activation, and hence GCN2-mediated eIF-2-alpha phosphorylation in amino acid-starved cells and subsequent down- regulation of protein synthesis (PubMed-1512650 [...] (258 aa)

SSB2
Cytoplasmic ATPase that is a ribosome-associated molecular chaperone, functions with J-protein partner Zuo1p; may be involved in the folding of newly-synthesized polypeptide chains; member of the HSP70 family; homolog of SSB1; May aid in the passage of the nascent polypeptide chain through the ribosome channel into the cytosol. Such an interaction could be crucial for continuous transport of the polypeptide; could serve to prevent the nascent polypeptide from interfering with translation by clogging the ribosome channel (613 aa)
