Descrição geral

Research area: Cell Signaling

Calmodulin (CaM) is a Ca2+-sensor protein containing four EF-hand motifs that bind to four Ca2+ ions. It is found ubiquitously in all eukaryotes.

Aplicação

Calmodulin from bovine testes has been used:

  • as a component of the reaction mixture in PhosphoSens assay to measure Ca2+/calmodulin-dependent protein kinase II α (CaMKIIα) substrate phosphorylation
  • to generate standard curve for the determination of in situ calmodulin concentration in tissues
  • as a ligand in radio-ligand binding for studying calmodulin affinity

Ações bioquímicas/fisiológicas

Calmodulin (CaM) aids in the Ca2+ signal transduction pathway in higher plants and animals. Ca2+ binding is required for CaM activation. Upon activation, CaM binds and activates numerous target proteins involved in a variety of cellular processes including regulation of plant metabolism, phytohormone signaling, ion transport, protein folding, protein phosphorylation and dephosphorylation, cell motility, exocytosis, and cytoskeletal assembly. In neurons, calcium-activated CaM helps in the regulation of glutamate receptors, modulation of proteins in signaling pathways, and regulation of voltage-gated calcium channels (VGCCs) activity.
Ca2+ binding protein that is required for activation of cyclic nucleotide-dependent phosphodiesterase. It is also a cofactor/activator of nitric oxide synthase, calcineurin, and many kinases including ATPase, myosin light chain kinase, and CAM kinase I, II, and III. It mediates ryanodine receptor activation by cyclic ADP ribose and is involved in intracellular Ca2+ homeostasis.

The neuronal membrane-associated periodic spectrin skeleton (MPS) contributes to neuronal development, remodeling, and organization. Post-translational modifications impinge on spectrin, the major component of the MPS, but their role remains poorly understood. One modification targeting spectrin is cleavage by calpains, a

Plasma membrane (Ca(2+)+Mg(2+))-ATPase and Ca(2+) transport activities, best characterized in human erythrocytes, are stimulated by calmodulin and thought to play a crucial role in the termination of cellular Ca(2+) signaling in all cells. In plasma membranes isolated from cultured porcine
