Aplicación
Histone is suitable for use:
- as a positive control in the in vitro kinase assay to examine the ability of Cdc2-cyclin B1 to phosphorylate GST-CD-4 protein
- in Cdk5 activity assay
- in histone H1 kinase assay
- as a Poly(ADP-ribose) (PAR) acceptor in the assessment of in vitro PAR polymerase activity
- as an acceptor of 32P from [γ-32P]ATP in order to measure protein kinase activity of lysate from small and large luteal cells
Acciones bioquímicas o fisiológicas
Histones are a group of proteins characterized by high levels of lysine and arginine that form reversible complexes with DNA. Based on the fractions, the molar mass of histones varies between 11-21kDa. Five different fractions have been isolated and characterized. They include H1 (lysine rich), H2a and H2b that are slightly lysine rich, H3 and H4 that are arginine rich. H1 acts as a link between "beads" (nu bodies) on the chromatin chain.

Depression is one of the most pervasive and debilitating psychiatric diseases, and the molecular mechanisms underlying the pathophysiology of depression have not been elucidated. Cyclin-dependent kinase 5 (Cdk5) has been implicated in synaptic plasticity underlying learning, memory, and neuropsychiatric disorders.
