Camk2b Gene Summary [Rat]

Enables calcium/calmodulin-dependent protein kinase activity; phospholipase binding activity; and protein kinase binding activity. A structural constituent of postsynaptic actin cytoskeleton. Involved in several processes, including cellular response to homocysteine; hippocampal neuron apoptotic process; and regulation of synapse organization. Acts upstream of or within long-term synaptic potentiation. Located in dendrite and perikaryon. Is active in glutamatergic synapse and postsynaptic density. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder 54. Orthologous to human CAMK2B (calcium/calmodulin dependent protein kinase II beta).

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Camk2b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
