... that result in the formation and localization of distinct cytoplasmic domains that are inherited by early blastomeres that develop autonomously. By applying various imaging techniques to the transparent eggs of Phallusia mammillata , we now define 9 events and phases in the reorganization of the surface...

... the functional significance of the cytoplasmic domains of the α PS1 , α PS2 and β PS subunits of the Drosophila Position Specific (PS) integrin family by analyzing the relationship between cytoplasmic domain structure and function in the context of a developing organism. By examining the ability of β PS...

... then produced in vitro a series of modifications of the wild-type P[mys + ] transposon, which encode β PS derivatives with mutations within the small and highly conserved cytoplasmic domain. In vivo analysis of these mutant transposons led to the following conclusions. The cytoplasmic tail of β PS is essential...
