Outline of Final Research Achievements

The holothurian body wall dermis is a catch connective tissue which changes its stiffness in response to stimulation. Substances which soften the dermis by working directly on its extracellular matrix had been unkown. We purified a softening protein from the dermis of a sea cucumber Stichopus chloronotus whose dermis dramatically softens in response to strong mechanical stimulation. We named this protein softenin. The apparent molecular mass of softenin is 20 kDa. Softenin softened the fresh dermis which contained living cells. The protein also softed the dermis whose cells had been disrupted. This result suggests that softenin softens the dermis by working directly on the extracellular matrix of the catch connective tissue.
