Retinoid receptors are asymmetrically oriented Retinoic acid receptor (RAR)/ Retinoid X receptor (RXR) heterodimers that bind to specific DNA sequences or Retinoic acid response elements (RAREs) in the promoters of a large number of retinoid-target genes [1], [2], ...

Prolactin is a polypeptide hormone secreted by the pituitary gland and to a lesser extent by numerous extrapituitary tissues. This hormone affects a great amount of physiological processes [1]. Numerous biological functions have been attributed to this hormone's ...

Key enzymes involved in retinoid metabolisms are alcohol and aldehyde dehydrogenases that convert retinols to aldehydes and aldehydes to carboxylic acids, respectively. The first oxidation reaction is catalyzed by a large number of enzymes from the Dehydrogenase/reductase (SDR family), and by classic ...

Beta-1 adrenergic receptor, Beta-2 adrenergic receptor and Beta-3 adrenergic receptor are ...
