BRM — Arabidopsis thaliana

Summary

AT2G46020, known as BRM or BRAHMA, encodes a protein with ATP-dependent chromatin remodeler activity, helicase activity, DNA-binding transcription factor activity, and proton:sugar symporter activity. It contains bromodomain and helicase domains and belongs to the SNF2 family. BRM is associated with chromatin organization, floral meristem identity, carpel development, cell fate specification, and vegetative phase change. It localizes to the nucleus, SWI-SNF complex, and nucleolus. The gene is linked to numerous traits including leaf morphology (rolled leaf, leaf area, leaf width), floral organ number, stamen number, petal color, inflorescence branching, harvest index, and boron sensitivity. It is also associated with flower development, disease response, early flowering, and phosphatidylcholine biosynthesis. Studies of related genes in other species link the family to cell division.
