MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene reduces the metastatic potential, but not the tumorogenicity, of human breast cancer and melanoma cell lines. The protein encoded by this gene localizes primarily to the nucleus and is a component of the mSin3a family of histone deacetylase complexes (HDAC). The protein contains two coiled-coil motifs and several imperfect leucine zipper motifs. Alternative splicing results in two transcript variants encoding different isoforms.

Protein Function and Prediction

Brms1 encodes BRMS1, a breast carcinoma metastasis suppressor gene that functions to suppress the spread of a primary tumor to a discontinuous site (1). BRMS1 domains include a glutamine-rich domain at the N-terminus, followed by two coiled-coil domains, and two C-terminal nuclear localization signals (2). Studies on the murine homolog of BRMS1 determined that it can suppress the metastatic capability of primary tumors, similar to the human protein (3). Further studies determined that one of the mechansims of BRMS1-dependent suppression of tumor metastasis involves inhibition of NF-κB activity and subsequent suppression of uPA expression in cancer cells (4).

Expression/Localization

Northern blot analysis determined that BRMS1 is ubiquitously expressed (5). Mouse Brms1 is highly expressed in testis, liver, kidney and heart; spleen and lungs showed moderate expression; and skeletal muscles showed minimal expression (3).
