Prelamin A Influences A Program Of Gene Expression In Regulation Of Cell Cycle Control, Christina N. Bridges

Electronic Theses and Dissertations

The A-type lamins are intermediate filament proteins that constitute a major part of the eukaryotic nuclear lamina—a tough, polymerized, mesh lining of the inner nuclear membrane, providing shape and structural integrity to the nucleus. Lamin A (LA) filaments also permeate the nucleoplasm, providing additional structural support, but also scaffolding numerous tethered molecules to stabilize, organize, and facilitate molecular interactions to accomplish critical functions of cellular metabolism. Over the past 2 decades, much attention has been focused on roles of LA in maintenance of nuclear structural integrity. Only since the late 1990s have scientists discovered the devastating effects of LA gene …
