The Punch locus of Drosophila melanogaster which encodes the pteridine biosynthetic enzyme, GTP cyclohydrolase, is genetically complex. Lethal alleles of the locus resolve into an array of interallelic complementation groups, and at least one class of mutations is developmentally specific, affecting GTP cyclohydrolase activity only in the heads of adults. All previously isolated Punch alleles were identified on the basis of a mutant eye color phenotype. By screening mutagenized chromosomes over Punch region deficiencies, we have now isolated new alleles on the basis of lethal and visible phenotypes. Most of these alleles fall into previously identified genetic classes, but two new classes of mutations were also found. One class contains two alleles that behave as dominant lethal mutations in some genetic backgrounds. The other class represents a second developmentally specific set of alleles that affect the function of the Punch locus only during embryogenesis.
