Cleavage and polyadenylation specificity factor

In vitro experiments show that correct modification of the 3 -end requires at least three protein factors the CPSF protein, the poly-A polymerase and the poly-A binding protein. The CPSF protein (CPSF cleavage and polyadenylation specificity factor) binds to the AAUAA signal and brings the poly-A polymerase to the polyadenylation site. The poly-A polymerase is supported by the poly-A binding protein. The latter binds to the poly-A sequence and is required for the transition from the phase of synthesis of short poly-A sequences to the formation of mature poly-A sequences (ca. 200 A-residues). [Pg.70]
