CAMK2A抗体;CAMK2A Antibody—艾普蒂

The CAMK2A antibody is a crucial tool in neuroscience research, targeting the calcium/calmodulin-dependent protein kinase II alpha (CaMKIIα) isoform. CaMKIIα is a serine/threonine kinase highly enriched in the brain, particularly in hippocampal and cortical neurons, where it plays a central role in synaptic plasticity, learning, and memory. This enzyme is activated by calcium influx, triggering autophosphorylation and sustained activity even after calcium levels decline—a mechanism critical for long-term potentiation (LTP). CAMK2A antibodies are widely used to study the expression, localization, and activation status of CaMKIIα in brain tissues or cultured neurons. They enable techniques like Western blotting, immunohistochemistry, and immunofluorescence to investigate its synaptic distribution, particularly in postsynaptic densities. These antibodies also help explore CaMKIIα's involvement in neurological disorders, including Alzheimer's disease, autism spectrum disorders, and schizophrenia, where aberrant signaling or expression has been observed. Many CAMK2A antibodies specifically recognize phosphorylated forms (e.g., at Thr286/287), allowing researchers to distinguish between active and inactive kinase states. Validation often includes testing in CaMKIIα knockout models to confirm specificity. As CaMKIIα dysfunction is implicated in multiple brain pathologies, these antibodies remain essential for unraveling molecular mechanisms underlying cognitive processes and disease pathways.
