BACKGROUND Post-transcriptional processing of pre-mRNA takes place in several steps and requires involvement of a number of RNA-binding proteins. How pre-mRNA processing is regulated is in large enigmatic. The catalytic (C) subunit of protein kinase A (PKA) is a serine/threonine kinase, which regulates numerous cellular processes including pre-mRNA(More)
Accumulation of the complex set of alternatively processed mRNA from the adenovirus major late transcription unit (MLTU) is subjected to a temporal regulation involving both changes in poly (A) site choice and alternative 3' splice site usage. We have previously shown that the adenovirus L4-33K protein functions as an alternative splicing factor involved in(More)
There are two major genes encoding the catalytic subunits of protein kinase A, Calpha and Cbeta. The functional significance of these isoforms is enigmatic. Lymphoid cells of the immune system express both Calpha and Cbeta. In this study we tested the role of Calpha and Cbeta in regulating immune cell reactivity to antigens using mice carrying a targeted(More)
Serine/arginine-rich splicing factor 1 (SRSF1), previously designated SF2/ASF, belongs to a family of SR proteins that regulate constitutive and alternative splicing. SRSF1 expression is increased in tumors from several tissues and elicits changes in key target genes involved in tumor genesis. Several protein kinases phosphorylate SRSF1, which regulates its(More)
