PAB-dependent poly(A)-specific ribonuclease subunit PAN3
 
Known also as: PAB1P-dependent poly(A)-nuclease

Known abbreviations: PAN3, YKL025C, ECM35

 

FUNCTION:
  • required for Poly (A) exoribonuclease activity - PAN plays an important role in the posttranscriptional maturation of mRNA poly(A) tails( one of the two subunits of PAN - the second one is Pan2p) (PMID: 9774670, 15169912)
  • positive activator of PAN activity (PMID: 15169912)
  • interaction with Pab1p (poly(A)-binding protein required for stimulation (via Pan3p) or inhibition (via Pbp1p) of poly(A) tail trimming) (PMID: 15169912, 17595167, 15630021)
CELLULAR LOCALIZATION:
 
Cytoplasm (PMID: 9774670, 15894541)
 
SUBUNIT STRUCTURE:
 
The PAN deadenylation complex is a heterodimer of a catalytic subunit PAN2 and a regulatory subunit PAN3. PAN3 interacts with PAB1, conferring substrate-specificity of the enzyme complex.
 
OTHER:
 
Pan3p contains PAN-2 motif (PMID: 17595167)
