Polyadenylate-binding protein-interacting protein 1 is a protein that in humans is encoded by the PAIP1 gene.{{cite journal | vauthors = Craig AW, Haghighat A, Yu AT, Sonenberg N | title = Interaction of polyadenylate-binding protein with the eIF4G homologue PAIP enhances translation | journal = Nature | volume = 392 | issue = 6675 | pages = 520–3 | date = Apr 1998 | pmid = 9548260 | doi = 10.1038/33198 | bibcode = 1998Natur.392..520C | s2cid = 10891925 }}{{cite journal | vauthors = Wiemann S, Weil B, Wellenreuther R, Gassenhuber J, Glassl S, Ansorge W, Böcher M, Blöcker H, Bauersachs S, Blum H, Lauber J, Düsterhöft A, Beyer A, Köhrer K, Strack N, Mewes HW, Ottenwälder B, Obermaier B, Tampe J, Heubner D, Wambutt R, Korn B, Klein M, Poustka A | title = Toward a catalog of human genes and proteins: sequencing and analysis of 500 novel complete protein coding human cDNAs | journal = Genome Res. | volume = 11 | issue = 3 | pages = 422–35 | date = Mar 2001 | pmid = 11230166 | pmc = 311072 | doi = 10.1101/gr.GR1547R }}{{cite web | title = Entrez Gene: PAIP1 poly(A) binding protein interacting protein 1| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=10605}}
Function
The protein encoded by this gene interacts with poly(A)-binding protein and with the cap-binding complex eIF4A. It is involved in translational initiation and protein biosynthesis. Overexpression of this gene in COS7 cells stimulates translation. Alternative splicing occurs at this locus and three transcript variants encoding three distinct isoforms have been identified.
Interactions
PAIP1 has been shown to interact with PABPC1.{{cite journal | vauthors = Roy G, De Crescenzo G, Khaleghpour K, Kahvejian A, O'Connor-McCourt M, Sonenberg N | title = Paip1 interacts with poly(A) binding protein through two independent binding motifs | journal = Mol.
