Alternative 5'-exons of the mouse cAMP-dependent protein kinase subunit RIalpha gene are conserved and expressed in both a ubiquitous and tissue-restricted fashion.
The activity of cAMP-dependent protein kinase is controlled by its regulatory subunits. Mouse RIalpha regulatory subunit expression is initiated from five different non-coding 5'-regions (exons 1a, 1b, 1c, 1d and 1e). This organization appears to be conserved among species. All mouse tissues accumulate exon 1a and 1b transcripts and most contain more 1b than 1a, except brain, heart and oesophagus. Exon 1d and 1e transcripts are found in several tissues, while exon 1c is testis-specific. All five transcripts are in RIalpha-rich tissues: gonads and adrenal glands.
