WebMay 11, 2015 · PABPN1 is an evolutionarily conserved protein that is best characterized for its role in mRNA polyadenylation, where it can stimulate poly (A) synthesis in vitro by increasing the processivity of the poly (A) polymerase ( 1, – 3 ). The requirement for PABPN1 during mRNA polyadenylation does not appear to be universal, however.

WebPABPN1 promotes intron excision in the context of 3′-end polyadenylation but not when bound to internal A-tracts. Importantly, the ability of PABPN1 to promote splicing requires its RNA binding and, to a lesser extent, PAP-stimulatory functions. WebApr 12, 2024 · PABPN1 also plays a role in polyadenylation-dependent decay or processing of nuclear RNAs by the exosome, including small nucleolar RNAs, long non-coding RNAs and abnormal mRNAs retained in the nucleus [ 21 – 25 ]. Defects in any of these molecular functions could participate in OPMD.
