title: Three-dimensional structures of proteins involved in programmed cell death.
abstract: Programmed cell death (apoptosis) is a controlled process by which unwanted cells are selectively eliminated. Several families of proteins including the Bcl-2, tumor necrosis factor receptor 1, and caspase families play essential roles in the regulation, signaling, and execution of the genetic cell death program. The recently described three-dimensional structures of members of these families elucidate the structural basis of their functions and provide insights into the mechanisms by which these proteins regulate apoptosis.
