STRINGSTRING
PAN3 protein (Saccharomyces cerevisiae) - STRING interaction network
"PAN3" - Essential subunit of the Pan2p-Pan3p poly(A)-ribonuclease complex, which acts to control poly(A) tail length and regulate the stoichiometry and activity of postreplication repair complexes 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

PAN3Essential subunit of the Pan2p-Pan3p poly(A)-ribonuclease complex, which acts to control poly(A) tail length and regulate the stoichiometry and activity of postreplication repair complexes; Regulatory subunit of the poly(A)-nuclease (PAN) deadenylation complex, one of two cytoplasmic mRNA deadenylases involved in mRNA turnover. PAN specifically shortens poly(A) tails of RNA when the poly(A) stretch is bound by poly(A)-binding protein PAB1, which is followed by rapid degradation of the shortened mRNA tails by the CCR4-NOT complex. Deadenylated mRNAs are then degraded by two alternative [...] (679 aa)

REX4
Putative RNA exonuclease possibly involved in pre-rRNA processing and ribosome assembly; Exoribonuclease involved in ribosome biosynthesis. Involved in the processing of ITS1, the internal transcribed spacer localized between the 18S and 5.8S rRNAs (289 aa)

REX3
RNA exonuclease; required for maturation of the RNA component of RNase MRP; functions redundantly with Rnh70p and Rex2p in processing of U5 snRNA and RNase P RNA; member of RNase D family of exonucleases; 3’ to 5’ exoribonuclease required for proper 3’ end maturation of MRP RNA and of the U5L snRNA (404 aa)

RNH70
3’-5’ exoribonuclease; required for maturation of 3’ ends of 5S rRNA and tRNA-Arg3 from dicistronic transcripts; 3’ exoribonuclease required for 5S rRNA maturation and for the proper maturation of the 5’ cistron of the tRNA-Arg3 dicistronic gene. Involved with REX2 in the maturation of the 5.8S rRNA, and with REX2 and REX3, in the 3’ processing of the U5L snRNA (553 aa)

PAB1
Poly(A) binding protein, part of the 3’-end RNA-processing complex, mediates interactions between the 5’ cap structure and the 3’ mRNA poly(A) tail, involved in control of poly(A) tail length, interacts with translation factor eIF-4G; Binds the poly(A) tail of mRNA. Appears to be an important mediator of the multiple roles of the poly(A) tail in mRNA biogenesis, stability and translation. In the nucleus, interacts with the nuclear cleavage factor IA (CFIA), which is required for both mRNA cleavage and polyadenylation. Is also required for efficient mRNA export to the cytoplasm. Acts in [...] (577 aa)

TUB3
Alpha-tubulin; associates with beta-tubulin (Tub2p) to form tubulin dimer, which polymerizes to form microtubules; expressed at lower level than Tub1p; Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha chain (445 aa)

DUN1
Cell-cycle checkpoint serine-threonine kinase required for DNA damage-induced transcription of certain target genes, phosphorylation of Rad55p and Sml1p, and transient G2/M arrest after DNA damage; also regulates postreplicative DNA repair; Transducer of the DNA damage signal. Phosphorylates SML1 on serine residues. Cooperates with the PAN deadenylation complex in the regulation of RAD5 mRNA levels and cell survival in response to replicational stress (513 aa)

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. Discovered because of its role in the contro [...] (837 aa)

POP2
RNase 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.
