His3.3A | Histone H3.3A; Variant histone H3 which replaces conventional H3 in a wide range of nucleosomes in active genes and is specifically enriched in modifications associated with active chromatin. Constitutes the predominant form of histone H3 in non-dividing cells and is incorporated into chromatin independently of DNA synthesis. Deposited at sites of nucleosomal displacement throughout transcribed genes, suggesting that it represents an epigenetic imprint of transcriptionally active chromatin. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular mach [...] (136 aa) | ||||
Gs2 | Glutamine synthetase 2 (Gs2) encodes an enzyme that converts glutamate to glutamine. It is expressed in the embryonic nervous system and regulates the size of glutamate neurotransmitter pools and synapse assembly. (373 aa) | ||||
Gs1 | Glutamine synthetase 1 (Gs1) encodes the mitochondrial enzyme that uses glutamate and ammonia as substrates to synthesize glutamine, which is a precursor of purine and pyrimidine synthesis. An adequate level of maternally supplied Gs1 product activity is necessary in the early embryonic development. High level of glutamine in mitochondria causes megamitochondrial formation in cells. (399 aa) | ||||
His3:CG31613 | Histone H3; Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. (136 aa) | ||||
betaTub56D | Tubulin beta chain; Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha chain. Belongs to the tubulin family. (456 aa) |
