CLONING AND CHARACTERIZATION OF TWO M-RNA TRANSCRIPTION FACTORS

摘要

DNA and protein sequences are disclosed for coactivators of mRNA transcription identified as p52 and p75. The p52 sequence also enhances ASF/SF2-mediated pre-mRNA splicing activity. The disclosure also includes specific binding agents (such as antibodies) that recognize these activators, methods of enhancing transcription using the activators, methods of treating disease caused by mutations, therapeutic compositions that include the activators, recombinant DNA molecules, probes, and transformed cells that incorporate the DNA sequence to express p52 and p75. The disclosure also includes methods of diagnosis and treatment of diseases caused by an underexpression of p52 and/or p75, including tumors such as breast adenocarcinomas.
