Control of germ cell nuclear behavior at fertilization by Tetrahymena 14-nm filament protein/citrate synthase

摘要

The Tetrahymena 14-nm filament protein is a cytoskeletal protein involvedin oral morphogenesis and in pronuclear behavior during fertilization. Based on immunofluorescence localization, we suggest that the protein is involved in some nuclear events, such as meiosis, formation of the gameticpronucleus.transferof the gametic pronudeus across a cell-cell junction, and zygote formation by pronuclear fusion (Numata et al. 1985).
