Prolyl 3,4-dihydroxylase TPA1

UniProtKB accession:  P40032

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Prolyl 3,4-dihydroxylase that catalyzes 3,4-dihydroxylation of 'Pro-64' of small ribosomal subunit uS12 (RPS23A and RPS23B), thereby regulating protein translation termination efficiency. Part of a messenger ribonucleoprotein (mRNP) complex at the 3'-UTR of mRNAs. It associates specifically with components of the translation termination complex and is involved in both translation termination and in regulation of normal mRNA decay through translation termination-coupled poly(A) shortening.
