High impact information on FIR1

  • It directly interacts with Fir1p, a component of the cleavage/polyadenylation complex [1].
  • Kinetic analyses of the respective polyadenylation reactions indicated that Pbp1p is a negative regulator of poly(A) nuclease (PAN) activity and that Fir1p and Ref2p are, respectively, a positive regulator and a negative regulator of poly(A) synthesis [2].
