Calcitonin gene-related protein

A fully amorphous (glassy) freeze-dried product, consisting of 5% of a calcitonin gene-related protein (CGRP), 95% lactose and 3% residual water, was heated gently in a sealed DSC capsule. Its Tg is shown by the endothermic step in Scan 1 of Figure 4. Heating beyond Tg makes a material susceptible to more or less rapid physical and/or chemical...

A mixture of high concentrations of cAMP and cAMP-dependent protein kinase increased the open probability of Kca channels reconstituted in a lipid bilayer (Savaria et al, 1992). p-Adrenergic stimulation increased Kca channel activity in whole-cell clamped rat myometrium (Anwer et al., 1992). In rabbit mesenteric arteries, calcitonin gene-related peptide (CGRP) appears to activate K xp channels through the mediation of protein kinase A (Quayle et al., 1994). These studies suggest that elevations in [cAMP] could hyperpolarize smooth muscle by opening K a or K xp channels.
