The process in which segments assume individual identities; exemplified in insects by the actions of the products of the homeotic genes.

The process whose specific outcome is the progression of the larval somatic muscle over time, from its formation to the mature structure.

The process whose specific outcome is the progression of the larval somatic muscle over time, from its formation to the mature structure.

Any process that stops, prevents, or reduces the frequency, rate or extent of the covalent addition of methyl groups to histones.

The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of ubiquitin, with ubiquitin-protein ligation catalyzed by an SCF (Skp1/Cul1/F-box protein) complex, and mediated by the proteasome.

Any process that stops, prevents, or reduces the frequency, rate or extent of the addition of a ubiquitin group to a histone protein.

The modification of histone H2A by addition of one or more ubiquitin groups.

The modification of histone H2A by addition of one or more ubiquitin groups.

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

The modification of histone H3 by the removal of a methyl group from lysine at position 36 of the histone.

The modification of histone H3 by the removal of a methyl group from lysine at position 36 of the histone.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

A ubiquitin ligase complex in which a cullin from the Cul1 subfamily and a RING domain protein form the catalytic core; substrate specificity is conferred by a Skp1 adaptor and an F-box protein. SCF complexes are involved in targeting proteins for degradation by the proteasome. The best characterized complexes are those from yeast and mammals (with core subunits named Cdc53/Cul1, Rbx1/Hrt1/Roc1).

A chromatin-associated multiprotein complex containing Polycomb Group proteins. In Drosophila, Polycomb group proteins are involved in the long-term maintenance of gene repression, and PcG protein complexes associate with Polycomb group response elements (PREs) in target genes to regulate higher-order chromatin structure.
