The RAD6 gene of Saccharomyces cerevisiae is required for postreplication repair of UV-damaged DNA, for induced mutagenesis, and for sporulation. The authors have mapped the transcripts and determined the nucleotide sequence of the cloned RAD6 gene. The RAD6 gene encodes two transcripts of 0.98 and 0.86 kilobases which differ only in their 3' termini. The transcribed region contains an open reading frame of 516 nucleotides. The rad6-1 and rad6-3 mutant alleles, which the authors have cloned and sequenced, introduce amber and ochre nonsense mutations, respectively into the open reading frame, proving that it encodes the RAD6 protein. The RAD6 protein predicted by the nucleotide sequence is 172 amino acids long, has a molecular weight of 19,704, and contains 23.3% acidic and 11.6% basic residues. Its most striking feature is the highly acidic carboxyl terminus: 20 of the 23 terminal amino acids are acidic, including 13 consecutive aspartates. RAD6 protein thus resembles high mobility group proteins HMG-1 and HMG-2, which each contain a carboxyl-proximal tract of acidic amino acids. 48 references, 6 figures.
