Keji is now a Senior Investigator at the Laboratory of Molecular Immunology at the NIH. He discovered that the mammalian SWI/SNF-like BAF complex contains b-actin as well as an actin-like protein and that actin plays a role in regulating the ATPase activity of the chromatin remodeling complex. One of his recent paper can be found in the Oct 2001 issue of Cell. Since then he went on to develop the methods of genome wide mapping of chromatin and transcriptional regulators (Chip-SAGE and CHIP-Seq Methods). Some of Keji’s recent work includes: Cell. 2008 Mar 7;132(5):887-98 and Cell. 2007 May 18;129(4):823-37. He can be contacted at zhaok@mail.nih.gov.
