Transcription activation by RNA polymerase II is a complicated process driven by combined, precisely coordinated action of a wide array of coactivator complexes, which carry out chromatin-directed activities and nucleate the assembly of the preinitiation complex on the promoter. Using various techniques, we have shown the existence of a stable coactivator(More)
The PBAF subtype of the mammalian chromatin remodeling SWI/SNF complex has wide and diverse functions in transcription regulation and development, being both transcription activator and repressor. However, a mechanism accounting for such functional diversity remains unclear. Human PHF10/BAF45a subunit of the PBAF complex plays an important role in brain(More)
SAYP is a dual-function transcription coactivator of RNA polymerase II. It is a metazoan-specific factor with regulated expression that is apparently involved in signaling pathways controlling normal development. In Drosophila, SAYP is maternally loaded into the embryo, participates in cell cycle synchronization in early syncytial embryos, and is(More)
SAYP is a dual-function transcriptional coactivator of RNA polymerase II. It is a metazoan-specific factor involved in different signaling pathways that control normal development. In Drosophila, SAYP is present in the organism from the early stages of development and participates in cell cycle synchronization at the blastoderm stage. SAYP is abundant in(More)
The production of major human heat shock protein Hsp70 (HSPA1A) in a eukaryotic expression system is needed for testing and possible medical applications. In this study, transgenic mice were produced containing wild-type human Hsp70 allele in the vector providing expression in the milk. The results indicated that human Hsp70 was readily expressed in the(More)
Mts1 (S100A4) protein is a marker of metastatic tumor cells, which is associated with a poor diagnostic prognosis for cancer progression. Therefore, it is important to study the S100A4 gene expression. According to our preliminary data, PHF10, a PBAF remodeling complex component, can play an important role in the transcription regulation of the S100A4 gene.(More)
Insulators are regulatory elements having two properties. First, they are able to disturb the interaction between promoters and enhancers/silencers. Second, they are able to block distribution of the heterochromatin. The best-studied are the Su(Hw)-dependent insulators of Drosophila melanogaster, activity of which is determined by the Su(Hw) protein. In(More)
Parkinson’s disease (PD) is the second most common neurodegenerative disorder and causes degeneration of dopaminergic neurons in the nigrostriatal system of the brain. PHF10 is one of the most important regulatory subunits of the SWI/SNF chromatin-remodeling protein complex, which controls the gene function and chromatin state in neurons. Two alternative(More)
