Protein Information (annotations from UniProt)

Database IDHIV0002087
UniProt IDQ58A45
Primary gene name(s)PAN3
Synonym gene name(s)unknown
Protein namePAB-dependent poly(A-specific ribonuclease subunit PAN3
Protein functionRegulatory subunit of the poly(A-nuclease, PAN deadenylation complex, one of two cytoplasmic mRNA deadenylases involved in general and miRNA-mediated mRNA turnover. PAN specifically shortens poly(A tails of RNA when the poly(A stretch is bound by poly(A-binding protein, PABP, which is followed by rapid degradation of the shortened mRNA tails by the CCR4-NOT complex. Deadenylated mRNAs are then degraded by two alternative mechanisms, namely exosome-mediated 3'-5' exonucleolytic degradation, or deadenlyation-dependent mRNA decaping and subsequent 5'-3' exonucleolytic degradation by XRN1. PAN3 acts as a positive regulator for PAN activity, recruiting the catalytic subunit PAN2 to mRNA via its interaction with PABP and to miRNA targets via its interaction with GW182 family proteins. {ECO:0000255|HAMAP-Rule:MF_03181, ECO:0000269|PubMed:14583602, ECO:0000269|PubMed:23932717}.
