WebbThe two catalytic steps of the pre-mRNA splicing reaction take place in the spliceosome, a dynamic complex of snRNAs and a large number of proteins (for reviews, see Moore et al. 1993; Kramer 1996;Reed and Palandjian 1997; Will 1997).In catalytic step I, the branch site adenosine carries out a nucleophilic attack on the 5′ splice site, generating the splicing … Webb2 mars 2006 · The U2 small nuclear ribonucleoprotein particle (snRNP) component SF3b1/SAP155 is the only spliceosomal protein known to be phosphorylated concomitant with splicing catalysis. DYRK1A is a nuclear protein kinase that has been localized to the splicing factor compartment. Here we describe the identification of DYRK1A as a protein …
