[[http://www.uniprot.org/uniprot/PABP1_HUMAN PABP1_HUMAN]] Binds the poly(A) tail of mRNA. May be involved in cytoplasmic regulatory processes of mRNA metabolism such as pre-mRNA splicing. Its function in translational initiation regulation can either be enhanced by PAIP1 or repressed by PAIP2. Can probably bind to cytoplasmic RNA sequences other than poly(A) in vivo. Involved in translationally coupled mRNA turnover. Implicated with other RNA-binding proteins in the cytoplasmic deadenylation/translational and decay interplay of the FOS mRNA mediated by the major coding-region determinant of instability (mCRD) domain. Involved in regulation of nonsense-mediated decay (NMD) of mRNAs containing premature stop codons; for the recognition of premature termination codons (PTC) and initiation of NMD a competitive interaction between UPF1 and PABPC1 with the ribosome-bound release factors is proposed.<ref>PMID:11051545</ref> <ref>PMID:18447585</ref> [[http://www.uniprot.org/uniprot/TNR6C_HUMAN TNR6C_HUMAN]] Plays a role in RNA-mediated gene silencing by micro-RNAs (miRNAs).
