Prohibitin-2 (PHB2)

Acts as a mediator of transcriptional repression by nuclear hormone receptors through recruitment of histone deacetylases (By similarity). Functions as an estrogen receptor (ER)-selective coregulator which potentiates the inhibitory activities of antiestrogens and represses the activity of estrogens.

Competes with NCOA1 for modulation of ER transcriptional activity. Probably involved in regulating mitochondrial respiration activity and in aging.
