Crystal structure of the BAZ2B TAM domain.

ABSTRACT: BAZ2B is a regulatory subunit of the ISWI (Imitation Switch) remodeling complex and engages in nucleosome remodeling. Loss-of-function and haploinsufficiency of BAZ2B are associated with different diseases. BAZ2B is a large multidomain protein. In addition to the epigenetic reader domains plant homeodomain (PHD) and bromodomain (BRD), BAZ2B also has a Tip5/ARBP/MBD (TAM) domain. Sequence alignment revealed that the TAM domains of BAZ2A and BAZ2B share 53% sequence identity. How the BAZ2A TAM domain bound with DNA has been characterized recently, however, the DNA binding ability and methylation preference, as well as the structural basis of the BAZ2B TAM domain are not studied yet. In this study, we measured the DNA binding affinity of the TAM domain of BAZ2B, and also determined its apo cr
