WebNov 6, 2024 · Poly (A)-binding proteins (PABPs) bind to the poly (A) tail present at the 3-prime ends of most eukaryotic mRNAs. PABPC4 or IPABP (inducible PABP) was isolated as an activation-induced T-cell mRNA encoding a protein. Activation of T cells increased PABPC4 mRNA levels in T cells approximately 5-fold.

WebJun 20, 2006 · PABP contains four RNA-recognition motifs (RRMs) and a proline-rich C-terminal region, which is N-terminal to a highly evolutionarily conserved sequence termed … WebMay 21, 2013 · In eukaryotes, the poly (A) binding protein (PABP) is a central regulator of both global and mRNA-specific translation. PABP simultaneously interacts with the 3′ poly (A) tail of the mRNA and the eukaryotic translation initiation factor 4G (eIF4G). These interactions circularize the mRNA and stimulate translation. folding screen for commercial

WebIn this work, we identified the Poly A Binding Protein (PABPC4) as a new NCoR1 interactor. Unexpectedly, we found that silencing of PABPC4 induced an oxidative phenotype in both C2C12 and MEF cells as indicated by increased oxygen consumption, mitochondria content, and reduced lactate production. ... Humans encode at least five PABP isoforms ... Poly(A)-binding protein (PAB or PABP) is an RNA-binding protein which triggers the binding of eukaryotic initiation factor 4 complex (eIF4G) directly to the poly(A) tail of mRNA which is 200-250 nucleotides long. The poly(A) tail is located on the 3' end of mRNA and was discovered by Mary Edmonds, who also … See more Cytosolic poly-A binding protein (PABPC) is made up of four RNA recognition motifs (RRMs) and a C-terminal region known as the PABC domain. RRM is the most common motifs for RNA recognition and is usually made up of … See more Rotavirus RNA-binding protein NSP3 interacts with eIF4GI and evicts the poly(A) binding protein from eIF4F. NSP3A by taking the place of PABP on eIF4GI, is responsible for the shut-off of cellular protein synthesis. Rotavirus mRNAs terminate a 3’ GACC … See more Multiple human genes encode different protein isoforms and paralogs of PABP, including PABPN1, PABPC1, PABPC3, PABPC4, PABPC5.
