    ..These results demonstrate that FLASH is an essential factor required for 3' end maturation of histone mRNAs in both vertebrates and invertebrates and suggest a potential link between this process and apoptosis. ..

    ..We demonstrate that Symplekin, CPSF73, and CPSF100 are present in a stable complex and interact with histone-specific processing factors...

    ..This localization depends on the RNA binding protein ypsilon schachtel. CPSF-73 and a number of mRNAs are localized at this same site, suggesting that Symplekin participates in cytoplasmic polyadenylation at tricellular junctions. ..

    A core cleavage complex (CCC) consisting of CPSF73, CPSF100, and Symplekin is required for cotranscriptional 3' end processing of all metazoan pre-mRNAs, yet little is known about the in vivo molecular interactions within this complex...
