Descriptions

CaMKII is one of the most important transducers of Ca2+signals in a variety of cell types and is highly conserved across animal species. The calmodulin-responsive regulatory segment forms a coiled coil structure that blocks peptide and ATP binding to the otherwise intrinsically active kinase domain.Ca2+/CaM removes the autoinhibitory regulatory segment located C-terminal to the kinase domain which releases the catalytic activity of the enzyme.

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
neuron projection A prolongation or process extending from a nerve cell, e.g. an axon or dendrite.
organelle Organized structure of distinctive morphology and function. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton, and prokaryotic structures such as anammoxosomes and pirellulosomes. Excludes the plasma membrane.

4 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
calmodulin binding Binding to calmodulin, a calcium-binding protein with many roles, both in the calcium-bound and calcium-free states.
