Descripción general

Research area: Cell Signaling

Calmodulin (CaM) ranks among the most highly conserved protein sequences, with only histone proteins H4 and H3, actin B, and ubiquitin showing greater evolutionary conservation. CaM is a primarily helical protein with N- and C-terminal domains, each containing two paired Ca2+-binding EF-hand motifs. These motifs, with pentagonal-bipyramidal geometry, feature a conserved 12-amino acid sequence (positions 1–12) within a canonical helix-loop-helix structure.[1]

Aplicación

Calmodulin, Bovine Brain, High Purity has been used to study melatonin-calmodulin interaction[2] and to activate Calcium–calmodulin (CaM)-dependent protein kinase IIa (CaMKII)a through in vitro incubation.[3]

Acciones bioquímicas o fisiológicas

Calmodulin (CaM) is a ubiquitous Ca2+-binding protein distributed in eukaryotic cells that serves as a major physiological effector for a wide range of cellular responses. The Ca2+-calmodulin complex is involved in the maintenance of intracellular Ca2+ homeostasis, as well as in the regulation of the intracellular concentration of other second messengers, such as cyclic AMP and inositol trisphosphate. Mutations in the CaM sequence can result in diverse and potentially life-threatening pathologies such as ventricular tachycardia, congenital arrhythmia, and long QT syndrome. These mutations have the capacity to modify CaM′s ability to bind to Ca2+ and its target proteins and peptides, thereby disrupting their subsequent activity. Ca2+/CaM complex and CaM-binding domains (CaMBDs) interactions influence memory formation, muscle contraction, cellular metabolism, and cytoskeletal rearrangements.[1]

Radiometric assays have widely been used for measuring protein kinase activity for decades. In addition, several non-radiometric kinase assay formats have been developed over the years, including luciferase-based and fluorescence-based assays. However, radiometric assays are still considered as the "gold

Melatonin (MEL) is a pleiotropic indolamine that reaches multiple intracellular targets. Among these, MEL binds to calmodulin (CaM) with high affinity. In presence of Ca2+, CaM binds to CaM-dependent kinase II (CaMKII). The Ca2+-CaM/CaMKII pathway regulates a myriad of brain
