Analysis of pediatric glioblastoma (GBM) tumors with mutations in H3F3A gene. Mutation of key residues in histone H3.3 are specific to GBM and highly prevalent in children and young adults. Results indicate that defects in chromatin architecture underlie pediatric GBM pathogenesis.

(Submitter supplied) The histone variant H3.3 is incorporated in a replication-independent manner at heterochromatic regions by the ATRX-DAXX histone chaperone complex. Here, we present a high-resolution x-ray crystal structure of an interaction surface between ATRX and DAXX. We used single amino acid substitutions in DAXX that abrogate formation of the complex to explore ATRX-dependent and -independent functions of DAXX. more...

(Submitter supplied) DAXX and ATRX are tumor suppressor proteins that form a complex with histone H3.3 chaperone and are frequently mutated in cancers with the alternative lengthening of telomeres (ALT), such as pediatric glioblastoma. Rapid loss of function of either DAXX or ATRX are not by themselves sufficient to induce the ALT phenotype. However, cells lacking DAXX or ATRX can be readily selected for ALT-like features. more...

(Submitter supplied) Histone chaperones prevent promiscuous histone interactions before chromatin assembly. They guarantee faithful deposition of canonical histones and functionally specialized histone variants into chromatin in a spatial- and temporally-restricted manner. Here, we identify the binding partners of the primate-specific and H3.3-related histone variant H3.Y using several quantitative mass spectrometry approaches, and biochemical and cell biological assays. more...

(Submitter supplied) The chromatin remodeller ATRX interacts with the histone chaperone DAXX, to deposit the histone variant H3.3 at sites of nucleosome turnover. ATRX is known to bind repetitive, heterochromatic regions of the genome including telomeres, ribosomal DNA and pericentric repeats many of which are putative G-quadruplex forming sequences (PQS). At these sites ATRX plays an ancillary role in a wide range of nuclear processes facilitating replication, chromatin modification and transcription. more...
