1.A.69.3.5
High energy light unresponsive protein 1, Lite1; chemoreceptor GUR-2 of 439 aas and 8 TMSs. It is a photoreceptor for short wavelength (UV) light that mediates UV-light-induced avoidance behavior (Edwards et al. 2008, Liu et al. 2010, Gong et al. 2016). It directly senses and absorbs both UV-A and UV-B light with very high efficiency (Gong et al. 2016). Absorption of UV-B but not UV-A light shows resistance to photobleaching. In contrast to other photoreceptors, it does not use a prosthetic chromophore to capture photons and only depends on its protein conformation. It may play a role in response to white light exposure (De Magalhaes Filho et al. 2018) as well as color detection (Ghosh et al. 2021).
