Neuroendocrine factors affecting the glycogen metabolism of purified Mytilus edulis glycogen cells: partial characterization of the putative glycogen mobilization hormone--demonstration of a factor that stimulates glycogen synthesis.
A putative glycogen mobilizing hormone (GMH) from the marine mussel Mytilus edulis L. has been partially characterized. GMH activity is present in the cerebral ganglia and the hemolymph serum and promotes the mobilization of glycogen in isolated glycogen cells. The cerebral GMH is trypsin sensitive and partially heat labile and has an apparent molecular mass of greater than 20 kDa. Following fractionation of cerebral extracts by molecular mass, a second factor, with a molecular mass of ca. 1.5 kDa, was discovered. This factor stimulates post-incubation incorporation of 14C into glycogen in isolated glycogen cells.
