The G protein-coupled receptor kinases (GRKs) participate with arrestins in the regulation and signal propagation of multiple G protein-coupled receptors (GPCR) of key physiological and pharmacological relevance in the cardiovascular system. The complex mechanisms of regulation of GRK expression, degradation and function are being unveiled gradually. The(More)
To investigate the potential involvement of adrenergic signaling in Alzheimer's disease (AD) pathogenesis, we performed genetic and functional studies of genes initiating the cascade. We chose two functional single-nucleotide polymorphisms (SNPs) in the beta1-adrenergic receptor (ADRB1) and the G protein beta3 subunit (GNB3) genes, respectively, and(More)
A central issue of myogenesis is the acquisition of identity by individual muscles. In Drosophila, at the time muscle progenitors are singled out, they already express unique combinations of muscle identity genes. This muscle code results from the integration of positional and temporal signalling inputs. Here we identify, by means of loss-of-function and(More)
