Pre-mRNA 3'-end-processing factor FIP1

Known also as: FIP1-like 1 protein,Factor interacting with PAP,Rearranged in hypereosinophilia

Known abbreviations: hFip1, FIP1L1, FIP1, RHE


Component of the cleavage and polyadenylation specificity factor (CPSF) complex that plays a key role in pre-mRNA 3'-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. FIP1L1 contributes to poly(A) site recognition and stimulates poly(A) addition. Binds to U-rich RNA sequence elements surrounding the poly(A) site. May act to tether poly(A) polymerase to the CPSF complex. 
Component of the cleavage and polyadenylation specificity factor (CPSF) complex, composed of CPSF1, CPSF2, CPSF3, CPSF4 and FIP1L1. Found in a complex with CPSF1, FIP1L1 and PAPOLA. Interacts with CPSF1, CPSF4, CSTF2, CSTF3 and PAPOLA. 
Note=A chromosomal aberration involving FIP1L1 is found in some cases of hypereosinophilic syndrome. Interstitial chromosomal deletion del4(q12q12) causes the fusion of FIP1L1 and PDGFRA (FIP1L1-PDGFRA).
