Abstract
Comparisons of proteins synthesized by the sexually differentiated and non-differentiated cells of T. mesenterica IFO-9313 (mating type ab) were performed with the soluble cell-fraction prepared by centrifugation at 25,000 .times. g for 30 min. Two-dimensional gel electrophoresis demonstrated that alteration in synthesis of some cellular proteins is induced in response to a mating hormone, tremerogen A-10, secreted by T. mesenterica IFO-9310 (mating type AB). Typical example of alteration is as follows: cellular proteins a (MW, 30,000) and b (MW, 13,000), located by a region of an isoelectric point, around 5.8, are remarkably decreased and increased, respectively, during sexual differentiation. Gene control for sexual differentiation may occur in response to the extracellular information substance.This publication has 1 reference indexed in Scilit:
