Sequence of the uaY12r18 and uaY12r3 alleles. The DNA and translated peptide sequence of the relevant portion of the uaY gene are shown for the uaY12r18, uaY12r3, and uaY+ alleles. Numbers indicate nucleotide position (+1 corresponding to the A of the uaY ATG). The uaY ATG and the wild-type NH2 terminal sequence of the UaY protein are given in boldface type, the ATG being in a larger type. The ATGs of uATG2 and uATG3, respectively, at −122 and −44 (see text) are underlined and in a larger type. uATG3 is deleted in uaY12r18. The inserted T between positions −63 and −62 in the uaY12r3 allele is in boldface type, underlined, and in a larger type.
