The layout of this reaction may differ from that in the pathway view due to the constraints in pathway layout

The PAN2-PAN3 exoribonuclease complex hydrolyzes the poly(A) tail of a mRNA, shortening the tail from about 200 adenosine residues to about 80 adenosine residues and yielding adenosine 5'-monophosphate. PAN2 is the exoribonuclease component of the complex; PAN3 is required for cellular localization. The poly(A)-binding protein (PABP) interacts with PAN3 and recruits the PAN2-PAN3 complex to mRNA.
