The parapinopsin of lamprey is a UV-sensitive opsin (λ max = 370 nm). [81] The teleosts have two groups of parapinopsins, one is sensitive to UV (λ max = 360-370 nm), the other is sensitive to …

2005年6月3日 · The parapinopsin recently found in the pineal organ of the lamprey is a UV-sensitive and bistable opsin with stable dark and light-activated states. VA-opsin is found in …

2017年1月31日 · We propose that UV and LW opsin gene duplications have restored the potential for trichromacy (three separate channels for colour vision) in beetles up to 12 times and more …

2023年3月3日 · Solar ultraviolet (UV) radiation-induced DNA damage is a major risk factor for skin cancer development. UV-induced redistribution of melanin near keratinocyte nuclei leads to …

2014年9月1日 · Here we characterize a UV opsin (LpUVOps1) that is expressed in all three types of L. polyphemus eyes. It is expressed in most photoreceptors in median ocelli, the only L. …

2022年1月7日 · Three distinct phylogenetic groups of visual opsins are found in insects, named long (LW), short (SW) and ultraviolet (UV) wavelength sensitive opsins. Recently, the LW …

2022年9月5日 · The free retinal chromophore maximally absorbs photons of light in the ultraviolet (UV) around 380 nm but its sensitivity is shifted to react to higher energy, shorter wavelengths, …

Objectives: To investigate the function and potential mechanism of opsin 5 (OPN5), a photoreceptor responsive to UVR wavelengths, in melanogenesis in HEMs. Methods: Melanin …

2024年4月16日 · Most vertebrates possess one rod opsin, the rhodopsin (RH1), often used for scotopic vision, and four basic types of cone opsins mediating colour vision: the short …

OPN3 triggers phosphorylation of activator protein 1 and ultimately upregulates MMP1, MMP2, MMP3 and MMP9 in NHDFs through activating Ca 2+ /calmodulin-dependent protein kinase II, …
