    摘要: With the aim of identifying potential cellular proteins that mediate the transcriptional regulation of YY1, a HeLa cDNA library was screened using the yeast two-hybrid system. A previously unknown protein interacting with YY1 was identified and named YY1AP. By using the 5'-rapid amplification of cDNA ends technique, the full-length cDNA of YY1AP was cloned and sequenced. The cDNA was 2253 bp in length and encoded an open reading frame of 750 amino acids. The chromosomal gene was made up of 10 exons separated by nine introns and is localized on chromosome 1 (1q21.3). Northern blot analysis revealed that YY1AP is ubiquitously expressed in various human tissues and cancer cell lines. Co-immunoprecipitation and immunostaining of cells further indicated that YY1AP co-localizes with YY1 in the nucleus. Furthermore, YY1AP was shown to be capable of enhancing the transcriptional activation of an YY1 responsive promoter. Subsequent analysis by glutathione S-transferase pull-down assay showed that YY1AP contained two YY1 binding regions. The transactivation region of YY1AP would seem to be localized within the section of amino acids 260-345. It is proposed that YY1AP is a novel co-activator of YY1.
