Tre1 GPCR initiates germ cell transepithelial migration by regulating Drosophila melanogaster E-cadherin (2008)

Kunwar, Prabhat S., Sano, Hiroko, Renault, Andrew D., Barbosa, Vitor, Fuse, Naoyuki, Lehmann, Ruth

Despite significant progress in identifying the guidance pathways that control cell migration, how a cell starts to move within an intact organism, acquires motility, and loses contact with its...

Mutation of a Drosophila gamma tubulin ring complex subunit encoded by discs degenerate-4 differentially disrupts centrosomal protein localization

Barbosa, Vitor, Yamamoto, Rochele R., Henderson, Daryl S., Glover, David M.

We have cloned the Drosophila gene discs degenerate-4 (dd4) and find that it encodes a component of the γ-tubulin ring complex (γTuRC) homologous to Spc98 of budding yeast. This provides the first...

l(3)malignant brain tumor and three novel genes are required for Drosophila germ-cell formation.

Yohn, Christopher B, Pusateri, Leslie, Barbosa, Vitor, Lehmann, Ruth

To identify genes involved in the process of germ-cell formation in Drosophila, a maternal-effect screen using the FLP/FRT-ovoD method was performed on chromosome 3R. In addition to expected...

A Maternal Screen for Genes Regulating Drosophila Oocyte Polarity Uncovers New Steps in Meiotic Progression

Barbosa, Vitor, Kimm, Naomi, Lehmann, Ruth

Meiotic checkpoints monitor chromosome status to ensure correct homologous recombination, genomic integrity, and chromosome segregation. In Drosophila, the persistent presence of double-strand DNA...
