Abstract

The snRNP E protein is one of several proteins associated with the U family of small nuclear RNAs that are involved in RNA processing. Isolation and characterization of the snRNP E protein cDNA sequences from mouse and chicken revealed a 100% conservation of the predicted amino acid sequence when compared to that of the human homologue. Further characterization of a genomic clone for the mouse snRNP E protein gene revealed that the 5′ untranslated region and the immediate 5′ upstream region have also been highly conserved: 72 and 70%, respectively. Conserved 5′ regions include multiple copies of the CTTCCG hexamer sequence which are involved in regulating transcription of the human snRNP E protein gene. Mobility shift assays using corresponding DNA fragments from both human and mouse reveal that both fragments can compete for binding of at least one common transcription factor. These studies demonstrate that along with the amino acid sequence conservation between human and mouse, the snRNP E protein gene has also maintained a high DNA sequence conservation within its basal promoter structure.
