UV-related proteins

UV-related proteins refers to a broad functional category of molecules involved in the cellular response to ultraviolet (UV) radiation, primarily focusing on the detection and repair of DNA damage. This group includes the Nucleotide Excision Repair (NER) machinery, such as the Xeroderma Pigmentosum (XP) protein family (XPA-XPG), and the UV-damaged DNA-binding (UV-DDB) complex, which specifically recognizes bulky lesions like cyclobutane pyrimidine dimers (Hoeijmakers, 2001; UniProt P58335). These proteins are essential for maintaining genomic stability by preventing the accumulation of mutations that lead to carcinogenesis. Deficiencies in these proteins are the primary cause of disorders like Xeroderma Pigmentosum, which is characterized by extreme photosensitivity and a significantly elevated risk of skin cancer (NIH GARD). While not a single therapeutic target, specific members of this group are the focus of DNA repair enhancement strategies, such as the topical delivery of exogenous repair enzymes like T4 endonuclease V to reduce the risk of skin cancer in high-risk patients (Dremel et al., 2022). Additionally, these proteins and their associated DNA lesions serve as critical biomarkers for assessing UV exposure and the efficacy of photoprotective agents.
