Global epigenetic and transcriptional trends among two rice subspecies and their reciprocal hybrids. 1997 Mar;22(3):75-7 Each chromosome contains a long molecule of DNA, which must fit into the cell nucleus. In addition to the major histones, which are deposited during DNA replication, all eukaryotes have variant types of H2A and H3 that are incorporated into chromatin during interphase and can impart unique properties to the nucleosomes they occupy [5]. 2016 May 1;143(9):1612-22. doi: 10.1242/dev.129973. 1992 Mar 30;300(2):167-70 Narration 00:00 Histone variants. In this study, we found that UHRF1 directly binds the EGR1 gene locus and that the loss of UHRF1 leads to upregulated EGR1 mRNA and protein expression, independent of TCR signaling, but changes neither the expression of the TCR complex nor the activation of ERK, indicating that UHRF1 regulates EGR1 expression through an epigenetic pathway. Histone acetylation in gene regulation | Briefings in Functional Despite these packaging constraints, nucleosomes must be able to allow access of sequence-specific binding proteins and enzymes such as DNA and RNA polymerases to DNA. Contrastingly, nuclear proteins were detected in human PLTs. Dinneny JR, Long TA, Wang JY, Jung JW, Mace D, Pointer S, Barron C, Brady SM, Schiefelbein J, Benfey PN. Other ones, such as Nona, solo-Oct, and CCGTC motifs, appear to modulate the functions of OCEs to enhance or repress the transcriptional level, possibly depending on the state of the cells. Chromatin-based gene regulation is effected by the interplay between sequence-specific DNA binding proteins, histone variants, histone modifying enzymes, chromatin-associated proteins, and ATP-dependent nucleosome remodelers, but how all of these components work together is still unclear [3].

Global epigenetic and transcriptional trends among two rice subspecies and their reciprocal hybrids. 1997 Mar;22(3):75-7 Each chromosome contains a long molecule of DNA, which must fit into the cell nucleus. In addition to the major histones, which are deposited during DNA replication, all eukaryotes have variant types of H2A and H3 that are incorporated into chromatin during interphase and can impart unique properties to the nucleosomes they occupy [5]. 2016 May 1;143(9):1612-22. doi: 10.1242/dev.129973. 1992 Mar 30;300(2):167-70 Narration 00:00 Histone variants. In this study, we found that UHRF1 directly binds the EGR1 gene locus and that the loss of UHRF1 leads to upregulated EGR1 mRNA and protein expression, independent of TCR signaling, but changes neither the expression of the TCR complex nor the activation of ERK, indicating that UHRF1 regulates EGR1 expression through an epigenetic pathway. Histone acetylation in gene regulation | Briefings in Functional Despite these packaging constraints, nucleosomes must be able to allow access of sequence-specific binding proteins and enzymes such as DNA and RNA polymerases to DNA. Contrastingly, nuclear proteins were detected in human PLTs. Dinneny JR, Long TA, Wang JY, Jung JW, Mace D, Pointer S, Barron C, Brady SM, Schiefelbein J, Benfey PN. Other ones, such as Nona, solo-Oct, and CCGTC motifs, appear to modulate the functions of OCEs to enhance or repress the transcriptional level, possibly depending on the state of the cells. Chromatin-based gene regulation is effected by the interplay between sequence-specific DNA binding proteins, histone variants, histone modifying enzymes, chromatin-associated proteins, and ATP-dependent nucleosome remodelers, but how all of these components work together is still unclear [3]. In the present paper, we review histone gene expression, highlighting the control mechanisms and key molecules involved in this process.
