Opsin 3 (OPN3) is a prominent photosensitive protein expressed in various skin cells, playing a key role in cutaneous light sensing.
-
2
OPN3 detects light signals, particularly ultraviolet and short-wavelength visible light, triggering multiple downstream signaling pathways.
-

Dysregulation of OPN3 signaling is linked to skin pathophysiological conditions, including UV damage, melanoma, and inflammatory skin diseases.
-
4
The signaling pathways activated by OPN3 regulate essential physiological processes such as pigmentation, immune response, and DNA repair.

OPN3 is considered a potential therapeutic target for treating photodermatoses and developing skincare products that modulate circadian rhythms.
