| 31. | The histone methyltransferases are specific to either lysine or arginine.
|
| 32. | Many corepressors can recruit histone deacetylase ( HDAC ) enzymes to promoters.
|
| 33. | The nucleosome octamer includes two copies of each histone H4.
|
| 34. | This protein acetylates both histone and non-histone proteins.
|
| 35. | This protein acetylates both histone and non-histone proteins.
|
| 36. | Histone acetylation / deacetylation alters chromatin structure and affects transcription.
|
| 37. | However, IRF2 also functions as a transcriptional activator of histone H4.
|
| 38. | This protein also mediates transcriptional repression through interaction with histone deacetylase 1.
|
| 39. | The encoded protein can phosphorylate myelin basic protein and histone in vitro.
|
| 40. | Other histone modifications have similar or opposite effects on transcription.
