OverviewNCBI Gene

The product of this gene is one of the four subunits of an enzyme which belongs to the serine/threonine protein kinase family, and to the Ca(2+)/calmodulin-dependent protein kinase subfamily. Calcium signaling is crucial for several aspects of plasticity at glutamatergic synapses. In mammalian cells the enzyme is composed of four different chains: alpha, beta, gamma, and delta. The product of this gene is a gamma chain. Many alternatively spliced transcripts encoding different isoforms have been described but the full-length nature of all the variants has not been determined.[provided by RefSeq, Mar 2011]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against CAMK2G can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads CAMK2G as an antibody target. Whether an autoantibody or antibody against CAMK2G could matter depends on whether native CAMK2G is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

CAMK2G is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.

Annotation status

The present source text does not explicitly label CAMK2G as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
