Our results reveal the composition of the compartmentalized phosphorylation/dephosphorylation system that regulates U snRNA export. This finding was surprising in that such a specific system for U snRNA export regulation is composed of two such universal MK-4305 kinase… Continue reading Supplementary Materials [Supplemental material] molcellb_28_1_487__index. cytoplasmic phosphatase for PHAX are CK2
