    Description: An octamer DNA sequence plays a critical role in directing transcription of immunoglobulin genes in B lymphocytes. A new technique of direct binding of radioactive DNA was used to screen a complementary DNA expression library from the BJAB cell line in lambda gt11 phage to derive molecular cDNA clones representing a putative B lymphocyte-specific octamer binding protein. The plaques were screened with DNA containing four copies of the octamer sequence and positive phage recombinants were identified. The fusion protein produced on inducing a lysogen of one phage bound to a monomeric octamer probe. The cDNA insert from this phage hybridized to messenger RNA found in B lymphocytes, but not in most other cells. Thus, this cDNA derives from a gene (oct-2) that specifies an octamer binding protein expressed preferentially in B lymphocytes, proving that, for at least one gene, a cell-specific transcription factor exists and its amount is controlled through messenger RNA availability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Staudt, L M -- Clerc, R G -- Singh, H -- LeBowitz, J H -- Sharp, P A -- Baltimore, D -- P01-CA42063/CA/NCI NIH HHS/ -- P30-CAL4051/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1988 Jul 29;241(4865):577-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Cambridge, MA 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3399892" target="_blank"〉PubMed〈/a〉

    Description: Specific short oligonucleotide sequences that enhance pre-mRNA splicing when present in exons, termed exonic splicing enhancers (ESEs), play important roles in constitutive and alternative splicing. A computational method, RESCUE-ESE, was developed that predicts which sequences have ESE activity by statistical analysis of exon-intron and splice site composition. When large data sets of human gene sequences were used, this method identified 10 predicted ESE motifs. Representatives of all 10 motifs were found to display enhancer activity in vivo, whereas point mutants of these sequences exhibited sharply reduced activity. The motifs identified enable prediction of the splicing phenotypes of exonic mutations in human genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fairbrother, William G -- Yeh, Ru-Fang -- Sharp, Phillip A -- Burge, Christopher B -- 1 R01 HG02439-01/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2002 Aug 9;297(5583):1007-13.

    Description: Mesenchymal stem cells (MSCs) are a pluripotent cell type that can differentiate into several distinct lineages. Two key transcription factors, Runx2 and peroxisome proliferator-activated receptor gamma (PPARgamma), drive MSCs to differentiate into either osteoblasts or adipocytes, respectively. How these two transcription factors are regulated in order to specify these alternate cell fates remains a pivotal question. Here we report that a 14-3-3-binding protein, TAZ (transcriptional coactivator with PDZ-binding motif), coactivates Runx2-dependent gene transcription while repressing PPARgamma-dependent gene transcription. By modulating TAZ expression in model cell lines, mouse embryonic fibroblasts, and primary MSCs in culture and in zebrafish in vivo, we observed alterations in osteogenic versus adipogenic potential. These results indicate that TAZ functions as a molecular rheostat that modulates MSC differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hong, Jeong-Ho -- Hwang, Eun Sook -- McManus, Michael T -- Amsterdam, Adam -- Tian, Yu -- Kalmukova, Ralitsa -- Mueller, Elisabetta -- Benjamin, Thomas -- Spiegelman, Bruce M -- Sharp, Phillip A -- Hopkins, Nancy -- Yaffe, Michael B -- CA042063/CA/NCI NIH HHS/ -- GM60594/GM/NIGMS NIH HHS/ -- GM68762/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2005 Aug 12;309(5737):1074-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Cancer Research, Department of Biology, Massachusetts Institute of Technology, 77 Massachusetts Avenue, E18-580, Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16099986" target="_blank"〉PubMed〈/a〉

    Description: Transcription of the mammalian genome is pervasive, but productive transcription outside of protein-coding genes is limited by unknown mechanisms. In particular, although RNA polymerase II (RNAPII) initiates divergently from most active gene promoters, productive elongation occurs primarily in the sense-coding direction. Here we show in mouse embryonic stem cells that asymmetric sequence determinants flanking gene transcription start sites control promoter directionality by regulating promoter-proximal cleavage and polyadenylation. We find that upstream antisense RNAs are cleaved and polyadenylated at poly(A) sites (PASs) shortly after initiation. De novo motif analysis shows PAS signals and U1 small nuclear ribonucleoprotein (snRNP) recognition sites to be the most depleted and enriched sequences, respectively, in the sense direction relative to the upstream antisense direction. These U1 snRNP sites and PAS sites are progressively gained and lost, respectively, at the 5' end of coding genes during vertebrate evolution. Functional disruption of U1 snRNP activity results in a dramatic increase in promoter-proximal cleavage events in the sense direction with slight increases in the antisense direction. These data suggest that a U1-PAS axis characterized by low U1 snRNP recognition and a high density of PASs in the upstream antisense region reinforces promoter directionality by promoting early termination in upstream antisense regions, whereas proximal sense PAS signals are suppressed by U1 snRNP. We propose that the U1-PAS axis limits pervasive transcription throughout the genome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3720719/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3720719/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Almada, Albert E -- Wu, Xuebing -- Kriz, Andrea J -- Burge, Christopher B -- Sharp, Phillip A -- GM-085319/GM/NIGMS NIH HHS/ -- P30 CA014051/CA/NCI NIH HHS/ -- P30-CA14051/CA/NCI NIH HHS/ -- R01 CA133404/CA/NCI NIH HHS/ -- R01 GM034277/GM/NIGMS NIH HHS/ -- R01 HG002439/HG/NHGRI NIH HHS/ -- R01-CA133404/CA/NCI NIH HHS/ -- R01-GM34277/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2013 Jul 18;499(7458):360-3. doi: 10.1038/nature12349.
