Abstract

The human small nuclear ribonucleoprotein E protein is an 11,000-dalton basic protein which is an integral component of several small nuclear ribonucleoprotein complexes involved in RNA processing reactions. Sequence analysis of the E protein multigene family reveals that at least one gene for this component of the RNA splicing machinery is interrupted by four introns. The exons of this gene are identical to two cDNA clones isolated from independent tissue sources and span approximately 9 kilobase pairs. Primer extension data indicated the presence of two major transcription start sites. The upstream region of the small nuclear ribonucleoprotein E protein gene does not contain TATA or CCAAT sequences within 175 nucleotides of the transcription start sites. However, the proximal upstream region does contain several similarities to the promoter regions of both snRNA genes and vertebrate ribosomal protein genes.
