Abstrakt, a DEAD Box Protein, Regulates Insc Levels and Asymmetric Division of Neural and Mesodermal Progenitors
Asymmetric cell division generates cell diversity in bacteria, yeast, and higher eukaryotes. In Drosophila, both neural and muscle progenitors divide asymmetrically. In these cells the Inscuteable (Insc) protein complex coordinates cell polarity and spindle orientation. Abstrakt (Abs) is a DEAD-box protein that regulates aspects of cell polarity in oocytes and embryos. We use a conditional alle...
متن کاملDevelopmental and cell biological functions of the Drosophila DEAD-box protein Abstrakt
BACKGROUND DEAD-box proteins are a large family of proteins found in bacteria, plants and animals, but only few have been analysed functionally. They are involved in the regulation of various aspects of RNA processing and metabolism, including splicing, transport and translation. The study of their function in multicellular organisms has been restricted to a few special cases, such as the Vasa ...
متن کاملThe Drosophila gene abstrakt, required for visual system development, encodes a putative RNA helicase of the DEAD box protein family
The molecular mechanisms underlying axonal pathfinding are not well understood. In a genetic screen for mutations affecting the projection of the larval optic nerve we isolated the abstrakt locus. abstrakt is required for pathfinding of the larval optic nerve, and it also affects development in both the adult visual system and the embryonic CNS. Here we report the molecular characterization of ...
متن کاملWeidemanagement bei Jungrindern auf der Alm mit einem GPS- und GSM-basierten Ortungssystem
Auf zwei Almen wurde der Einsatz von GPS-basierten Trackingsystemen an acht Jungrindern (Herdengröße: 36 Tiere) über einen Almsommer untersucht. Die Trackingsysteme wiesen eine statische Genauigkeit im Median zwischen 7,5 und 11,2 m auf. Der Anbringungsort des Systems am Hals (dorsal vs. lateral, getestet an einem Tier) hatte einen signifikanten Einfluss auf die im Median empfangene Anzahl an D...
