UV-stimulated scaffold protein A (UVSSA) gene, a causal gene of UV-hypersensitivity syndrome, has a C. elegans homolog—uvs-1.
uvs-1 mutant animals are defective in repairing CPD lesions and are hypersensitive to UV during development.
UV-B irradiation reduces the life span of uvs-1 animals.
uvs-1 and csb-1 function epistatically to promote UV-resistance.
uvs-1 mutant animals are hypersensitive to the transcription-blocking DNA lesions induced by illudin-M.
