The CPSF … WebDec 23, 2002 · Genetic studies in yeast — both budding yeast Saccharomyces cerevisiae and fission yeast Schizosaccharomyces pombe — have identified a set of essential gene products associated with cleavage and polyadenylation. These factors have also been biochemically characterised. These studies have initially ascribed a seemingly more …
WebApr 11, 2016 · Cleavage and polyadenylation specificity factor 30 (CPSF30) is a key protein involved in pre-mRNA processing. CPSF30 contains five Cys 3 His domains (annotated as “zinc-finger” domains). WebThe specific cleavage requires CPSF and one or more apparently dispensable factors. One is known as the cleavage stimulation factor (CStF) or cleavage factor 1 (CFI), which increases the efficiency and specificity of cleavage. CStF/CFI is not involved in polyadenylation.
WebThrombin formation requires cleavage of prothrombin at two sites, R271 and R320, by the prothrombinase complex composed of factor Xa (fXa), cofactor Va (fVa), ... and this may well be a major role played by fVa in the prothrombinase complex. After cleavage at R320, prothrombin transitions to the active intermediate meizothrombin that is also a ... WebCleavage and polyadenylation specificity factor subunit 5 (CPSF5) is an enzyme that in humans is encoded by the NUDT21 gene. It belongs to the Nudix family of hydrolases..
