Relative affinity constants by electrospray ionization and Fourier transform ion cyclotron resonance mass spectrometry: calmodulin binding to peptide analogs of myosin light chain kinase [PDF]
Synthetic RS20 peptide and a set of its point-mutated peptide analogs have been used to analyze the interactions between calmodulin (CaM) and the CaM-binding sequence of smooth-muscle myosin light chain kinase both in the presence and the absence of Ca2+.

Kv7 channels can function without constitutive calmodulin tethering.
M-channels are voltage-gated potassium channels composed of Kv7.2-7.5 subunits that serve as important regulators of neuronal excitability. Calmodulin binding is required for Kv7 channel function and mutations in Kv7.2 that disrupt calmodulin binding ...

The calcium/calmodulin-dependent protein kinase (CCaMK) is regulated by free Ca2+ and Ca2+-loaded calmodulin. This dual binding is believed to be involved in its regulation and associated physiological functions, although direct experimental evidence for

Activation and inactivation of neuronal nitric oxide synthase: characterization of Ca2+-dependent [125I]Calmodulin binding [PDF]
Constitutive isoforms of nitric oxide synthase (NOS) are activated by transient binding of Ca(2+)/Calmodulin. Here, we characterize the binding of Calmodulin to purified neuronal NOS (nNOS). [125I]Calmodulin bound to a single class of non-interacting and

Interactions of Calmodulin With the Multiple Binding Sites of Cav1.2 Ca2+ Channels
Although calmodulin binding to various sites of the Cav1.2 Ca2+ channel has been reported, the mechanism of the interaction is not fully understood. In this study we examined calmodulin binding to fragment channel peptides using a semi-quantitative pull ...

Use of top-down and bottom-up fourier transform ion cyclotron resonance mass spectrometry for mapping calmodulin sites modified by platinum anticancer drugs [PDF]
Calmodulin (CaM) is a highly conserved, ubiquitous, calcium-binding protein; it binds to and regulates many different protein targets, thereby functioning as a calcium sensor and signal transducer.

A novel calmodulin-like protein from the liver fluke, Fasciola hepatica [PDF]
An 18.2 kDa protein from the liver fluke, Fasciola hepatica has been identified and characterised. The protein shows strongest sequence similarity to egg antigen proteins from Schistosoma mansoni, Schistosoma japonicum and Clonorchis sinensis.
