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.

4 GO annotations of cellular component

Name Definition
axon cytoplasm Any cytoplasm that is part of a axon.
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.
perikaryon The portion of the cell soma (neuronal cell body) that excludes the nucleus.

8 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.
calmodulin-dependent protein kinase activity Calmodulin-dependent catalysis of the reactions: ATP + a protein serine = ADP + protein serine phosphate; and ATP + a protein threonine = ADP + protein threonine phosphate.
identical protein binding Binding to an identical protein or proteins.
metal ion binding Binding to a metal ion.
protein serine kinase activity Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate.
protein serine/threonine/tyrosine kinase activity Catalysis of the reactions: ATP + a protein serine = ADP + protein serine phosphate; ATP + a protein threonine = ADP + protein threonine phosphate; and ATP + a protein tyrosine = ADP + protein tyrosine phosphate.
transmembrane transporter binding Binding to a transmembrane transporter, a protein or protein complex that enables the transfer of a substance, usually a specific substance or a group of related substances, from one side of a membrane to the other.

7 GO annotations of biological process

Name Definition
MAPK cascade An intracellular protein kinase cascade containing at least a MAPK, a MAPKK and a MAP3K. The cascade can also contain an additional tiers: the upstream MAP4K. The kinases in each tier phosphorylate and activate the kinase in the downstream tier to transmit a signal within a cell.
medium-term memory The memory process that deals with the storage, retrieval and modification of information received at a time ago that is intermediate between that of short and long term memory (30min - 7hrs in Drosophila melanogaster).
peptidyl-serine phosphorylation The phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine.
peptidyl-threonine phosphorylation The phosphorylation of peptidyl-threonine to form peptidyl-O-phospho-L-threonine.
positive regulation of gene expression Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product (protein or RNA).
protein phosphorylation The process of introducing a phosphate group on to a protein.
serotonin biosynthetic process The chemical reactions and pathways resulting in the formation of serotonin (5-hydroxytryptamine), a monoamine neurotransmitter occurring in the peripheral and central nervous systems, also having hormonal properties.
