Description_x000D_ General description_x000D_ Monoclonal Anti-Histone Deacetylase 5 (HDAC5) (mouse IgG1 isotype) is derived from the HDAC5-35 hybridoma produced by the fusion of mouse myeloma cells (NS1) and splenocytes from BALB/c mice immunized with a synthetic peptide. Mammalian HDACs can be divided into three classes according to sequence homology. Class II consists of the yeast Hda1-like proteins HDAC4, HDAC5, HDAC6, HDAC7, HDAC9 and HDAC10. Histone deacetylase 5 (HDAC5) is a histone deacetylase, located on human chromosome 17q21._x000D_ Application_x000D_ Anti-Histone Deacetylase 5 (HDAC5) antibody, Mouse monoclonal has been used in:_x000D_ • western blotting_x000D_ • immunostaining_x000D_ • enzyme-linked immunosorbent assay (ELISA)_x000D_ • immunocytochemistry_x000D_ • immunoprecipitation_x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, and 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Histone deacetylase 5 (HDAC5) promotes progression of the cell cycle, cell proliferation and apoptosis. HDAC5 activity is important for the differentiation of muscle cells by binding, through its N-terminal domain, to the myocyte enhancer factor-2 (Mef2) protein, thus repressing expression of MEF2 downstream genes. Overexpression of HDAC5 in different cancer cells suppresses their growth by induction of apoptosis in a p53-independent manner. Reduced expression of the protein is observed in colon cancer and acute myeloid leukemia.
