['To study the correction phenotype of temperature sensitive mutant rad24LR of S. cerevisiae and to clone wild human functional homologue.', 'The temperature sensitive mutant rad24LR was studied by complementation test. Transformation of rad24LR was performed with human cDNA expression library to screen for reversion phenotype.', 'RAD24L can complement the radiation sensitive phenotype of the mutation. Its homologue of human cDNA was cloned by screening transformed rad24LR with human expression library for reversion phenotype.'] Is [ Human hR24L gene involved in DNA excision repair and recombination repair ]?
