NCoR1 mediates papillomavirus E8;E2C transcriptional repression.
The papillomavirus E2 open reading frame encodes the full-length E2 protein as well as an alternatively spliced product called E8;E2C. E8;E2C has been best studied for the high-risk human papillomaviruses, where it has been shown to regulate viral genome levels and, like the full-length E2 protein, to repress transcription from the viral promoter that directs the expression of the viral E6 and ...
متن کاملHistone sumoylation is associated with transcriptional repression.
Histone proteins are subject to modifications, such as acetylation, methylation, phosphorylation, ubiquitination, glycosylation, and ADP ribosylation, some of which are known to play important roles in the regulation of chromatin structure and function. Here we report that histone H4 is modified by small ubiquitin-related modifier (SUMO) family proteins both in vivo and in vitro. H4 binds to th...
متن کاملMeCP2-Dependent Transcriptional Repression Regulates Excitatory Neurotransmission
Mutations in the transcriptional repressor, methyl-CpG binding protein 2 (MeCP2), result in a neurodevelopmental disorder called Rett Syndrome (RTT) . Based on the neurological phenotypes observed in Rett patients, we examined the potential role of MeCP2 in synaptic function. We compared elementary properties of synaptic transmission between cultured hippocampal neurons from MeCP2 knockout and ...
متن کاملA high-resolution map of transcriptional repression
Turning genes on and off is essential for development and homeostasis, yet little is known about the sequence and causal role of chromatin state changes during the repression of active genes. This is surprising, as defective gene silencing underlies developmental abnormalities and disease. Here we delineate the sequence and functional contribution of transcriptional repression mechanisms at hig...
