... interacts with F-actin via b-catenin and a-catenin; b-catenin binds to cadherin and a-catenin, which in turn interacts with F-actin (Fig. 3A) [24]. Thus b-catenin plays a pivotal role in the regulation ... synchronous increases in intracellular [Ca 2+ ], as described below. Synchronous increases in intracellular [Ca 2+ ] and disassembly of cadherin–catenin complexes The cytoplasmic do...

... functions towards the circadian clock. miRNAs are single-stranded, nonprotein-coding RNA molecules, approximately 19–25 nucleotides in length. By binding to the complementary sites in the 3¢UTRs ... composed of several self-sustaining feedback loops. In this study, we describe another mechanism impinging on the core compo- nents of the circadian clock. Using a forward genetic screen,...
