The modification of histone H3 by the removal of a methyl group from lysine at position 4 of the histone.

The process of formation of spermatozoa, including spermatocytogenesis and spermiogenesis.

Any process that modulates the frequency, rate or extent of gene expression such that an expression pattern recurs with a regularity of approximately 24 hours.

The modification of histone H3 by the removal of a methyl group from lysine at position 4 of the histone.

Any process that results in the specification, formation or maintenance of the physical structure of eukaryotic chromatin.

That part of the nuclear content other than the chromosomes or the nucleolus.

A structure found most metazoan nucleoli, but not usually found in lower eukaryotes; surrounded by the dense fibrillar component; the zone of transcription from multiple copies of the pre-rRNA genes is in the border region between these two structures.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

Any of a number of evolutionarily conserved histone deacetylase complexes (HDACs) containing a core consisting of a paired amphipathic helix motif protein (e.g. Sin3p in S. cerevisiae, Pst1 in S. pombe or Sin3A in mammals) at least one class I histone deacetylase (e.g. Rpd3p in S. cerevisiae, Clr6 in S. pombe, or HDAC1 and HDAC2 in mammals), and at least one WD40 repeat protein (e.g. Ume1p in S. cerevisiae, Prw1 in S. pombe, or RbAp46 and RbAp48 in mammals). These complexes also contain a variable number of other proteins that direct histone binding, DNA binding, or add other functionality to the complex.

That part of the nuclear content other than the chromosomes or the nucleolus.
