STRINGSTRING
POP2 protein (Saccharomyces cerevisiae) - STRING interaction network
"POP2" - RNase of the DEDD superfamily, subunit of the Ccr4-Not complex that mediates 3' to 5' mRNA deadenylation 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

POP2RNase of the DEDD superfamily, subunit of the Ccr4-Not complex that mediates 3’ to 5’ mRNA deadenylation; Acts as probably catalytic component of the CCR4-NOT core complex, which in the nucleus seems to be a general transcription factor, and in the cytoplasm the major mRNA deadenylase involved in mRNA turnover. In vitro, POP2 has 3’- exoribonuclease activity with a preference for poly(A) RNAs, but also degrades poly(U) and poly(C) RNAs. Is part of a glucose- sensing system involved in growth control in response to glucose availability (433 aa)    
Predicted Functional Partners:
CCR4
Component of the CCR4-NOT transcriptional complex, which is involved in regulation of gene expression; component of the major cytoplasmic deadenylase, which is involved in mRNA poly(A) tail shortening; Acts as catalytic component of the CCR4-NOT core complex, which in the nucleus seems to be a general transcription factor, and in the cytoplasm the major mRNA deadenylase involved in mRNA turnover. CCR4 has 3’-5’ RNase activity with a strong preference for polyadenylated substrates and also low exonuclease activity towards single-stranded DNA.
