Histone deacetylase 2 (HDAC 2) knockout mouse embryonic stem cell line

Responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Histone deacetylases act via the formation of large multiprotein complexes. Histone deacetylases (HDAC) 1 and 2 are highly similar enzymes that help regulate chromatin structure as the core catalytic components of corepressor complexes. Although tissue-specific deletion of HDAC1 and HDAC2 has demonstrated functional redundancy, germ-line deletion of HDAC1 in the mouse causes early embryonic lethality, whereas HDAC2 does…
