Transcriptional repression of frequency by the IEC-1-INO80 complex is required for normal Neurospora circadian clock function
Rhythmic activation and repression of the frequency (frq) gene are essential for normal function of the Neurospora circadian clock. WHITE COLLAR (WC) complex, the positive element of the Neurospora circadian system, is responsible for stimulation of frq transcription. We report that a C2H2 finger domain-containing protein IEC-1 and its associated chromatin remodeling complex INO80 play importan...
متن کاملSki is a component of the histone deacetylase complex required for transcriptional repression by Mad and thyroid hormone receptor.
The N-CoR/SMRT complex containing mSin3 and histone deacetylase (HDAC) mediates transcriptional repression by nuclear hormone receptors and Mad. The proteins encoded by the ski proto-oncogene family directly bind to N-CoR/SMRT and mSin3A, and forms a complex with HDAC. c-Ski and its related gene product Sno are required for transcriptional repression by Mad and thyroid hormone receptor (TRbeta)...
متن کاملHistone Deacetylase Activity Is Required for Full Transcriptional Repression by mSin3A
Members of the Mad family of bHLH-Zip proteins heterodimerize with Max to repress transcription in a sequence-specific manner. Transcriptional repression by Mad:Max heterodimers is mediated by ternary complex formation with either of the corepressors mSin3A or mSin3B. We report here that mSin3A is an in vivo component of large, heterogeneous multiprotein complexes and is tightly and specificall...
متن کاملThe ZiN/POZ domain of ZF5 is required for both transcriptional activation and repression.
ZF5 is a ubiquitously expressed protein originally identified by its ability to bind and repress the murine c-myc promoter. It contains five C-terminal zinc fingers and a conserved N-terminal ZiN/POZ domain. This motif, found in a growing number of zinc finger proteins, can inhibit DNA binding and mediate dimerization [Bardwell, V.J. and Treisman,R. (1994) Genes Dev., 8,1664-1677]. In the curre...
متن کاملTranscriptional repression by neuron-restrictive silencer factor is mediated via the Sin3-histone deacetylase complex.
A large number of neuron-specific genes characterized to date are under the control of negative transcriptional regulation. Many promoter regions of neuron-specific genes possess the repressor element repressor element 1/neuron-restrictive silencing element (RE1/NRSE). Its cognate binding protein, REST/NRSF, is an essential transcription factor; its null mutations result in embryonic lethality,...
