Dopey Family, Member 1 (DOPEY1)

DOPEY1, Belongs to the dopey family.May be involved in protein traffic between late Golgi and early endosomes. DopA homologues from Saccharomyces cerevisiae (Dop1), Candida albicans, Caenorhabditis elegans, Rattus norvegicus and Homo sapiens have been identified from genome sequencing projects. S. cerevisiae DOP1 is essential for viability and, like DopA, affects cellular morphogenesis. dopA encodes a large protein (207 kDa) containing several putative domains, including three leucine zipper-like domains. Strains with either the temperature-sensitive dopA1(ts) allele, which alters one of the leucine zippers, or the null deltadopA allele, had abnormal morphology of the vegetative hyphae, delayed and asynchronous initiation of asexual development, aberrant morphogenesis of the conidiophore and an early block in the sexual cycle.
