WebStable adhesion is dependent on interactions of the cytoplasmic domain of the cadherins with a group of intracellular proteins, the catenins. In the present study, we have detected the expression of α-,β-, and γ-catenins in human osteoblasts, which assemble with cadherins to form two distinct complexes containing cadherin and α-catenin ... WebThe cell-intrinsic properties arise from a cleavage of a cell with asymmetrically expressed maternal cytoplasmic determinants (proteins, small regulatory RNAs and mRNA). Thus, the fate of the cell depends on factors secreted into its cytoplasm during cleavage. ...
