Phospho-specific Antibody for Cam Kinase II

Tech ID: 20301 / UC Case 2003-450-0


Calcium/calmodulin-dependent protein kinases (CaM kinases) are a family of proteins involved in many biological processes throughout the human body. These processes include metabolism, electrolyte regulation, gene expression, and many brain functions critical to learning and memory. Calmodulin is a protein that, when bound to calcium, causes activation of CaM kinase. However, when the calcium/calmodulin complex falls off an already activated CaM kinase, a phenomenon known as inhibitory phosphorylation occurs. Phosphates become attached to specific amino acids on CaM kinase, leading to decreased sensitivity to the calcium/calmodulin signal and an overall inhibition of the kinase. This inhibition has been shown to play an important role in the regulation of CaM Kinase II, a protein found in the brain which is essential to learning and memory.


UCLA researchers have developed a polyclonal antibody that recognizes the phosphorylated amino acid sequence involved in the inhibition of CaM kinase II. This is distinct from previous antibodies specific only for the phosphorylated sequence involved in the activation process. Research into inhibitory phosphorylation has yielded potential therapeutic targets in certain forms of mental retardation.
