NIPP1 is a ubiquitous regulator of protein phosphatase-1 (PP1) and is targeted to the splicing factor storage sites (speckles) in the nucleus by its forkhead-associated domain. We show here that NIPP1 is also a component of the spliceosomes in HeLa cell-splicing extracts and that the interaction with the spliceosomes requires a functional forkhead… CONTINUE READING
