Keratin Proteins

In addition to protecting epithelial cells from mechanical stress, keratins regulate cytoarchitecture, cell growth, proliferation, apoptosis, and organelle transport. In this issue, Vijayaraj et al. (2009. J. Cell Biol. doi:10.1083/jcb.200906094) expand our understanding of how keratin proteins participate in the regulation of protein synthesis through their analysis of mice lacking the entire type II keratin gene cluster.

Cell Growth And Differentiation

Calmodulin (CaM) is a major intracellular Ca2+ mediator protein involved in cell growth and differentiation. To evaluate calmodulin function in lung, it was necessary to construct a gene that encodes a high-affinity calmodulin binding peptide, since chemically synthesized calmodulin inhibitors lack binding and targeting specificity. This calmodulin inhibitor peptide gene was targeted to type II epithelial cells in transgenic mice using the human surfactant protein C promoter. Neutralization of calmodulin function in progenitor type II epithelial pneumocytes alters epithelial cell growth and differentiation, which prevents branching morphogenesis of the bronchial tree. Newborn transgenic animals have undeveloped lungs. This study indicates that type II lung epithelial cells require functional CaM for proliferation and development. The targeting of specific inhibitor peptides to a single lung cell type is an approach to evaluate the role of calmodulin, the ubiquitous calcium-dependent regulator protein, in lung development and disease.
