While structures of yeast SAGA (ySAGA) have been reported, there are ...The SAGA complex is a regulatory hub involved in gene regulation, chromatin modification, DNA damage repair and signaling. While structures of yeast SAGA (ySAGA) have been reported, there are noteworthy functional and compositional differences for this complex in metazoans. Here we present the cryogenic-electron microscopy (cryo-EM) structure of human SAGA (hSAGA) and show how the arrangement of distinct structural elements results in a globally divergent organization from that of yeast, with a different interface tethering the core module to the TRRAP subunit, resulting in a dramatically altered geometry of functional elements and with the integration of a metazoan-specific splicing module. Our hSAGA structure reveals the presence of an inositol hexakisphosphate (InsP) binding site in TRRAP and an unusual property of its pseudo-(Ψ)PIKK. Finally, we map human disease mutations, thus providing the needed framework for structure-guided drug design of this important therapeutic target for human developmental diseases and cancer.

Additional density corresponding to the linkers I259-I277 and J232-J247 can be observed at the interface between the core and TRRAP module, but could not be clearly assigned to one of the subunits. Connected loop density is observed but not modeled due to insufficient information on register, linker length, or confidence in backbone assignment: A1689-A1692, A1722-A1728, A1769-A1786, A1800-1805, A1823-A1837, A2181-A2192, A2209-A2217, A2239-A2248, A2291-A2299, C27-C30 Density corresponding to H182-H187 is observed, might be explained by multiple main chain conformations and was not modeled. Continuous density for linkers connecting an unassigned (UNK) with an assigned region, corresponding to D48-D51 and D118, is observed but was omitted, because the register in the unassigned (UNK) regions could not be assigned. Region I174-I185 and its connection is observed in the LocSpiral (Kaur, S. et al., bioRxiv 2020) filtered multibody maps. The cis-peptide bond of A3698 is defined by coulomb density. Mass spectrometry did not distinguish between the isoforms (uniprot) Q8NEM7-2 and Q8NEM7-3 of SUPT20H (chain C). Both isoforms distinguish primarily in disordered regions. In an ordered region, Q8NEM7-2 and Q8NEM7-3 distinguish by an insertion of one amino acid (Gln56 in Q8NEM7-2), which is better explained by Q8NEM7-3. Mass spectrometry did not distinguish between the isoforms (uniprot) O94864 and O94864-2 (chain D). Both isoforms distinguish by two N-terminal amino acids in a disordered region. The sequence numbering corresponds to O94864. Mass spectrometry indicated that (uniprot) Q9HBM6 (TAF9B) and Q16594 (TAF9) were present in the sample. TAF9B explains the density slightly better (chain E), however, it is possible that both subunits are present in the complex. Mass spectrometry did not distinguish between the isoforms (uniprot) Q16514 and Q16514-2 (chain G). Both isoforms distinguish in the disordered N-terminus. Due to a 5x higher abundance of Q16514 in all cell types and the requirement of the longer N-terminal domain for transcriptional activation (Hamard, P.-J., et al. Oncogene. 2005 May 12;24(21):3472-83.), Q16514 was modeled. Mass spectrometry indicated that (uniprot) O15265 (ATXN7), Q9ULK2 (ATXN7L1), and Q5T6C5 (ATXN7L2) were present in the sample. The density is explained best by ATXN7 and ATXN7L1 (in this order) (chain N), however, it is possible that a mixture of all subunits is present. The modeled isoforms of all other subunits were determined either by mass spectrometry or density fit. The ligand INOSITOL HEXAKISPHOSPHATE (IHP) was identified by density fit and homology to mTORC2 (PDB 6ZWO, Scaliola A., et al. Sci Adv. 2020 Nov 6;6(45)). Additional density close to P4 might be explained by an alternative conformation or an ordered water molecule. Only the conformation with the better geometry was modeled.

2019年1月31日: EMDBのIDの桁数の変更

EMDBのIDの桁数の変更

  • EMDBエントリに付与されているアクセスコード(EMDB-ID)は4桁の数字(例、EMD-1234)でしたが、間もなく枯渇します。これまでの4桁のID番号は4桁のまま変更されませんが、4桁の数字を使い切った後に発行されるIDは5桁以上の数字(例、EMD-12345)になります。5桁のIDは2019年の春頃から発行される見通しです。
  • EM Navigator/万見では、接頭語「EMD-」は省略されています。
