摘要
Chick brain extract contains protein factors for neurite outgrowth from embryonic chick telencephalic neurons in dissociated cell cultures. In the course of purification of the factors using a bioassay system, a 41 kDa protein was detected to be one of the factors. Immunoblot analysis showed that this protein is identical to actin. In addition, G-actin purified from rabbit skeletal muscle exhibits neurite outgrowth activity in the same dose-dependent manner as the 41 kDa protein. The same bioassay carried with other purified proteins did not show such a remarkable activity. © 1992 Academic Press, Inc.
