Location(s) of BRMS1 and corresponding activities. BRMS1 is a transcription co-repressor and can shuttle between nucleus and cytoplasm. BRMS1 levels are governed by ubiquitin-mediated degradation. In the nucleus, it shows inhibition of some transcripts and up-regulation others. However, some of these regulations may be due to its cytoplasmic activities (such as deacetylation of NFκB members). The ultimate impact of BRMS1 on a specific tumor cell appears to be tumor type and context-dependent.
