Application
All trans-Retinal has been used:
- in optogenetic experiments
- in electrophysiological experiment
- to study the effect of AKR1B10 (aldo-keto reductase (AKR) superfamily member) on the conversion of retinal to retinol in the airway epithelium
- in decidual transformation of human endometrial stromal cells
Biochem/physiol Actions
All-trans retinal is converted to retinoic acid in vivo by the action of retinal dehydrogenase. Retinoic acid is a ligand for both the retinoic acid receptor (RAR) and the retinoid X receptor (RXR) that act as transcription factors to regulate the growth and differentiation of normal and malignant cells. Retinal isomers are also chromophores that bind to opsins, a family of G-protein-linked transmembrane proteins, to form photosensitive receptors in visual and nonvisual systems. All-trans retinal is a potent photosensitizer.
General description
All trans-Retinal is one of the major derivatives of vitamin A group. A variety of food serves as a source of vitamin A. It is predominant in liver and among the brightly colored vegetables.
