Growth and form of secretory granules involves stepwise assembly but not differential sorting of a family of secretory proteins in Paramecium.

Journal of cell science - 1 Mar 2001

Vayssié L, Garreau de Loubresse N, Sperling L

Abstract excerpt

Paramecium trichocysts are voluminous secretory vesicles consisting of a spindle-shaped body surmounted by a tip that serves to anchor them at exocytotic sites in the plasma membrane. This constrained shape is conferred by the proteins stored in the vesicles, which form an insoluble three-dimensional crystalline array. The constituent polypeptides (Trichocyst Matrix Proteins, TMPs), which assemble during...
