(Submitter supplied) The Retinoblastoma-like pocket proteins p130 and p107 act as gatekeepers of the cell cycle through their activity within the DREAM (Dp/Rb-like/E2F/MuvB) transcriptional repressor complex. The goal of this study was to address how the pocket protein contributes to DREAM complex assembly and function on chromatin by utilizing a protein null mutant of the only C. elegans pocket protein LIN-35. We performed ChIP-seq of C. more...

(Submitter supplied) The highly conserved DREAM transcriptional repressor complex contains an RB-like pocket protein, an E2F-DP transcription factor heterodimer, and the 5-subunit MuvB complex. Using CRISPR/Cas9 targeted mutagenesis, we disrupted the interaction between the sole Caenorhabditis elegans pocket protein LIN-35 and the MuvB subunit LIN-52. A triple alanine substitution of LIN-52's LxCxE motif (3A) severed LIN-35-MuvB association and caused classical DREAM mutant phenotypes, including synthetic multiple vulvae, high-temperature arrest, and ectopic expression of germline genes in the soma. more...

(Submitter supplied) The mammalian Retinoblastoma (RB) family including pRB, p107, and p130 represses E2F target genes through mechanisms that are not fully understood. In D. melanogaster, RB-dependent repression is mediated in part by the multisubunit protein complex Drosophila RBF, E2F, and Myb (dREAM) that contains homologs of the C. elegans synthetic multivulva class B (synMuvB) gene products. Using an integrated approach combining proteomics, genomics, and bioinformatic analyses, we identified a p130 complex termed DP, RB-like, E2F, and MuvB (DREAM) that contains mammalian homologs of synMuvB proteins LIN-9, LIN-37, LIN-52, LIN-54, and LIN-53/RBBP4. more...

(Submitter supplied) As part of a study of the function of the C. elegans DREAM complex, here we have used ChIP-seq to analyze the patterns of histone variant HTZ-1/H2A.Z and various histone modifications in lin-35(n745) mutants. In addition, we have used RNA-seq to analyze gene expression in lin-35 and htz-1 mutants as compared with wild-type L3 larvae.

(Submitter supplied) The DREAM (DP, Retinoblastoma [Rb]-like, E2F, and MuvB) complex controls cellular quiescence by repressing cell cycle and other genes, but its mechanism of action is unclear. Here we demonstrate that two C. elegans THAP domain proteins, LIN-15B and LIN-36, co-localize with DREAM and function by different mechanisms for repression of distinct sets of targets. LIN-36 represses classical cell cycle targets by promoting DREAM binding and gene body enrichment of H2A.Z. more...

(Submitter supplied) Microarray-based expression profiling of dissected gonads from efl-1, dpl-1 and lin-35 mutants reveals that EFL-1 and DPL-1 promote expression of an extensively overlapping set of target genes, consistent with the expectation that these two proteins function as a heterodimer. Regulatory regions upstream of many of these target genes have a canonical E2F binding site, suggesting that their regulation by EFL-1/DPL-1 is direct. more...

(Submitter supplied) The Rb/E2F tumor suppressor regulates gene expression to control the onset and timing of differentiation in many different cell types during development. This critical function makes Rb/E2F a frequent target for inactivation in tumors of diverse tissue origin. However, the mechanisms by which Rb/E2F governs tissue-specific gene regulation in vivo are poorly understood. We have determined the genome-wide binding profiles for components of the C. more...

(Submitter supplied) LIN-35 is the single C. elegans ortholog of the mammalian pocket protein family members, pRb, p107, and p130. To gain insight into the roles of pocket proteins during development, a microarray analysis was performed with lin-35 mutants. Stage-specific regulation patterns were revealed, indicating that LIN-35 plays diverse roles at distinct developmental stages. LIN-35 was found to repress the expression of many genes involved in cell proliferation in larvae, an activity that is carried out in conjunction with E2F. more...

(Submitter supplied) Here we uncover antagonistic regulation of transcript levels in the germline of Caenorhabditis elegans hermaphrodites. The histone methyltransferase MES-4 marks genes expressed in the germline with methylated Lys36 on histone H3 (H3K36me) and promotes their transcription; MES-4 also represses genes normally expressed in somatic cells and genes on the X chromosomes. The DRM complex, which includes E2F/DP and Retinoblastoma homologs, affects germline gene expression and prevents excessive repression of X-chromosome genes. more...

(Submitter supplied) synMuv B proteins, including LIN-15B, are necessary to repress the expression of germline-promoting genes in the soma during embryonic and early larval development in C. elegans. The goal of this research was to determine if changes to histone modifications could underlie the misexpression of germline genes in these mutants. We performed ChIP-seq on four histone modifications in wild type and three synMuv B mutants at two temperatures to assess these changes.

(Submitter supplied) DRM is a conserved transcription factor complex that includes E2F/DP and pRB family proteins and plays important roles in development and cancer. Here we perform microarray expression profiling analysis of lin-54, a DNA-binding member of the DRM complex. To identify genes regulated by LIN-54 in soma and germline, we analyzed wild-type and lin-54 mutant C. elegans embryos and isolated germlines. We chose embryos because they consist primarily of somatic cells, at a developmental stage with both active cell divisions and dynamic developmental gene expression programs. more...
