Binding of the chromatin remodeling complex NoRC to RNA complementary to the rDNA promoter mediates transcriptional repression. TIP5, the largest subunit of NoRC, is involved in recruitment to rDNA by interactions with promoter-bound TTF-I, pRNA, and acetylation of H4K16. TIP5 domains that recognize posttranslational modifications on histones are essential for recruitment of NoRC to chromatin, but how these reader modules recognize site-specific histone tails has remained elusive. Here, we report crystal structures of PHD zinc finger and bromodomains from human TIP5 and BAZ2B in free form and bound to H3 and/or H4 histones. PHD finger functions as an independent structural module in recognizing unmodified H3 histone tails, and the bromodomain prefers H3 and H4 acetylation marks followed by a key basic residue, KacXXR. Further low-resolution analyses of PHD-bromodomain modules provide molecular insights into their trans histone tail recognition, required for nucleosome recruitment and transcriptional repression of the NoRC complex. 履歴 登録 2014年4月22日 登録サイト : RCSB / 処理サイト : RCSB改定 1.0 2014年5月21日 Provider : repository / タイプ : Initial release改定 1.1 2015年4月22日 Group : Database references改定 1.2 2024年2月28日 Group : Data collection / Database references / Derived calculationsカテゴリ : chem_comp_atom / chem_comp_bond ... chem_comp_atom / chem_comp_bond / database_2 / pdbx_struct_conn_angle / struct_conn / struct_ref_seq_dif / struct_site Item : _database_2.pdbx_DOI / _database_2.pdbx_database_accession ... _database_2.pdbx_DOI / _database_2.pdbx_database_accession / _pdbx_struct_conn_angle.ptnr1_auth_asym_id / _pdbx_struct_conn_angle.ptnr1_auth_comp_id / _pdbx_struct_conn_angle.ptnr1_auth_seq_id / _pdbx_struct_conn_angle.ptnr1_label_asym_id / _pdbx_struct_conn_angle.ptnr1_label_atom_id / _pdbx_struct_conn_angle.ptnr1_label_comp_id / _pdbx_struct_conn_angle.ptnr1_label_seq_id / _pdbx_struct_conn_angle.ptnr2_auth_asym_id / _pdbx_struct_conn_angle.ptnr2_auth_seq_id / _pdbx_struct_conn_angle.ptnr2_label_asym_id / _pdbx_struct_conn_angle.ptnr3_auth_asym_id / _pdbx_struct_conn_angle.ptnr3_auth_comp_id / _pdbx_struct_conn_angle.ptnr3_auth_seq_id / _pdbx_struct_conn_angle.ptnr3_label_asym_id / _pdbx_struct_conn_angle.ptnr3_label_atom_id / _pdbx_struct_conn_angle.ptnr3_label_comp_id / _pdbx_struct_conn_angle.ptnr3_label_seq_id / _pdbx_struct_conn_angle.value / _struct_conn.pdbx_dist_value / _struct_conn.ptnr1_auth_asym_id / _struct_conn.ptnr1_auth_comp_id / _struct_conn.ptnr1_auth_seq_id / _struct_conn.ptnr1_label_asym_id / _struct_conn.ptnr1_label_atom_id / _struct_conn.ptnr1_label_comp_id / _struct_conn.ptnr1_label_seq_id / _struct_conn.ptnr2_auth_asym_id / _struct_conn.ptnr2_auth_seq_id / _struct_conn.ptnr2_label_asym_id / _struct_ref_seq_dif.details / _struct_site.pdbx_auth_asym_id / _struct_site.pdbx_auth_comp_id / _struct_site.pdbx_auth_seq_id
