A puzzle piece found in unraveling the wiring of the brain

...m one site to another in the cell. Neurons in the fly brain that lack sec15 not only display aberrant wiring patterns, but also show misplacement of proteins required for correct nerve cell contact choices. Most of these cell contact proteins were previously known to display highly dynamic expression p...

Programmable cells: Engineer turns bacteria into living computers

... various body parts of a mature organism. In fruit fly embryos, for example, the first cells are thought to differentiate into the head, abdomen and other parts based on the concentration of chemical signals that are emitted from the ends of the embryo. In addition to conducting laboratory experiments, ...

Molecular Motors Cooperate In Moving Cellular Cargo, Study Shows

... toxic substances) inside specially cultured fruit fly cells. This was the first time the imaging technique had been used inside a living cell. "Our measurements show that both dynein and kinesin carry the peroxisomes in a step-by-step fashion, moving about 8 nanometers per step," said Selvin, who also ...

PANTHER Protein Classification System Database 5.0

...The PANTHER system functional annotations of fruit fly genes have beenavailable for two years as part of an ongoing collaboration withFlyBase. “The task of performing functional annotation of genomes ischallenging. Too often we rely simply on transitive annotation based ona BLAST match. The PANTHER syste...

...tein and some of its functions in the common fruit fly Drosophila are understood. "But no one knew what Staufen1 did in human cells," said Maquat, even though its presence in mammalian cells has been recognized for several years. "We were surprised to find that Staufen1 interacts with Upf1," she added. ...

Molecular biology fills gaps in knowledge of bat evolution

... of large fruit-eating bats from the tropics, that fly mostly during the day - known to biologists as megabats - emerged from four major lineages of smaller and more widely dispersed, mostly insect-eating, night-flying bats, known as microbats. These microbats - also known for their highly specialized ec...
