B2 genes are short repeated sequences which are transcribed by RNA polymerase III. Abundant transcripts accumulate in embryonic and transformed cells, but transcripts are rare or absent from normal differentiated cell types. During retinoic acid-induced differentiation of P19 embryonal carcinoma cells, an early transient increase in B2 RNA levels is followed by a rapid drop in expression. The marked changes in B2 RNA levels are most likely due to transcriptional modulation since B2 RNA stabilities are unaffected by differentiation. At least four short-lived B2 RNAs with apparent lengths of 150, 180, 240, and 500 nucleotides were characterized. The two larger RNAs are polyadenylated and are more stable in cells. A cDNA of a B2 gene was isolated which was over 99% identical to the consensus sequence. This B2 cDNA can be transcribed in human cells and yields at least two distinct transcripts. We propose a model for B2 RNA metabolism which describes transcription, posttranscriptional modification and processing, and nucleocytoplasmic transport.
