Saturation analysis indicated that [3H]-SR ( nM) labelled a single class of binding sites in rat cerebral cortex membranes with high affinity (KD +/-Bmax +/- 20 fmol mg-1 protein), although kinetic data indicated the existence of negative cooperativity between the binding sites.(ABSTRACT TRUNCATED AT WORDS)Cited by:   Amylin, a amino acid peptide structurally related to calcitonin gene-related peptide, is synthesized in and released along with insulin from pancreatic beta-cells.

Amylin is proposed to act as an endocrine partner to insulin, in part through actions upon skeletal muscle that promote cycling of gluconeogenic precursors to liver.

We report here that binding sites. In the adult rat brain, the calcium-binding protein parvalbumin is preferentially associated with spontaneously fast-firing, metabolically active neurons and coexists with gamma-amino-butyric acid (GABA) in cortical inhibitory interneurons.

Protease-activated receptor-1 (PAR1) is the first identified and prototype member of an established PAR family. In addition to the traditional role of PAR1 in thrombosis, hemostasis and vascular biology, its role in tumor biology is currently emerging [1,2,3]. We have established a novel link between hPar1 and.

The C-terminal regions of the four human plasma membrane Ca 2+ pump isoforms 1a-d generated from alternatively spliced RNA have been expressed in Escherichia coli, and the recombinant proteins have been purified to a very high degree.
