The use of transgenic mouse models to reveal the functions of Ca² ⁺ buffer proteins in excitable cells

Schwaller, Beat

In: Biochimica et Biophysica Acta (BBA) - General Subjects, 2012, p. -

Background Cytosolic Ca² ⁺ buffers are members of the large family of Ca² ⁺-binding proteins and are essential components of the Ca² ⁺ signaling toolkit implicated in the precise regulation of intracellular Ca² ⁺ signals. Their physiological role in excitable cells has been investigated in vivo by analyzing the phenotype of mice either lacking one of the Ca² ⁺ buffers or...

Lack of Calbindin-D28k alters response of the murine circadian clock to light

Stadler, Frédéric ; Schmutz, Isabelle ; Schwaller, Beat ; Albrecht, Urs

In: Chronobiology International, 2010, vol. 27, no. 1, p. 68-82

A strong stimulus adjusting the circadian clock to the prevailing light-dark cycle is light. However, the circadian clock is reset by light only at specific times of the day. The mechanisms mediating such gating of light input to the CNS are not well understood. There is evidence that Ca²⁺ ions play an important role in intracellular signaling mechanisms, including signaling cascades...
