NOC2L Proteins and Enzymes

NOC2L is a transcriptional corepressor with inhibitor of histone acetyltransferase (INHAT) activity. NOC2L or NIR (Novel INHAT Repressor) is ubiquitously expressed throughout embryonic development and adulthood. It is a potent transcriptional corepressor that is not blocked by histone deacetylase inhibitors and is capable of silencing both basal and activator-driven transcription. NOC2L directly binds to nucleosomes and core histones and prevents acetylation by histone acetyltransferases, thus acting as a bona fide INHAT.
