Abstract: Eukaryotic transcription is dependent on specific histone modifications. Their recognition by chromatin readers triggers complex processes relying on the coordinated association of transcription ...Eukaryotic transcription is dependent on specific histone modifications. Their recognition by chromatin readers triggers complex processes relying on the coordinated association of transcription regulatory factors. Although various modification states of a particular histone residue often lead to differential outcomes, it is not entirely clear how they are discriminated. Moreover, the contribution of intrinsically disordered regions outside of the specialized reader domains to nucleosome binding remains unexplored. Here, we report the structures of a PWWP domain from transcriptional coactivator LEDGF in complex with the H3K36 di- and trimethylated nucleosome, indicating that both methylation marks are recognized by PWWP in a highly conserved manner. We identify a unique secondary interaction site for the PWWP domain at the interface between the acidic patch and nucleosomal DNA that might contribute to an H3K36-methylation independent role of LEDGF. We reveal DNA interacting motifs in the intrinsically disordered region of LEDGF that discriminate between the intra- or extranucleosomal DNA but remain dynamic in the context of dinucleosomes. The interplay between the LEDGF H3K36-methylation reader and protein binding module mediated by multivalent interactions of the intrinsically disordered linker with chromatin might help direct the elongation machinery to the vicinity of RNA polymerase II, thereby facilitating productive elongation.

Jan 31, 2019. EMDB accession codes are about to change! (news from PDBe EMDB page)

EMDB accession codes are about to change! (news from PDBe EMDB page)

  • The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
  • The EM Navigator/Yorodumi systems omit the EMD- prefix.
