SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily b, member 1
Gene Summary
The protein encoded by SMARCB1 is part of a complex that relieves repressive chromatin structures, allowing the transcriptional machinery to access its targets more effectively. The encoded nuclear protein may also bind to and enhance the DNA joining activity of HIV-1 integrase. SMARCB1 has been found to be a tumor suppressor, and mutations in it have been associated with malignant rhabdoid tumors.
