| three calpains and ecdysone receptor in the land crab gecarcinus lateralis: sequences, expression and effects of elevated ecdysteroid induced by eyestalk ablation. | crustacean muscle has four calpain-like proteinase activities (cdp i, iia, iib and iii) that are involved in molt-induced claw muscle atrophy, as they degrade myofibrillar proteins in vitro and in situ. using pcr cloning techniques, three full-length calpain cdnas (gl-calpb, gl-calpm and gl-calpt) were isolated from limb regenerates of the tropical land crab gecarcinus lateralis. all three had highly conserved catalytic (dii) and c2-like (diii) domains. gl-calpb was classified as a typical, or e ... | 2005 | 16081615 |
