Comparison of BTB Superfamilies in Physcomitrella patens and Arabidopsis thaliana.

Abstract

Following their synthesis, proteins in cells can be modified in a variety of ways. These modifications may modulate the protein's activity, localization, interactions with other molecules, or stability. One such modification is the covalent attachment of a small globular protein called ubiquitin (Ub). Dr. Gingerich has previously characterized the BTB family in a dicotyledenous flowering plant, Arabidopsis thaliana. In this studied, I have begun to characterize the family in a simple nonvascular moss, Physcomitrella patens.
