In Caenorhabditis elegans three pairs of neurons, AFD, AIY, and AIZ, play a key role in thermosensation. The LIM homeobox gene ceh-14 is expressed in the AFD thermosensory neurons. ceh-14 mutant animals display athermotactic behaviors, although the neurons are still present and differentiated. Two other LIM homeobox genes, ttx-3 and lin-11, function in the(More)
engrailed is a homeobox gene essential for developmental functions such as differentiation of cell populations and the onset of compartment boundaries in arthropods and vertebrates. We present the first functional study on engrailed in an unsegmented animal: the nematode Caenorhabditis elegans. In the developing worm embryo, ceh-16/engrailed is(More)
Although acetylated alpha-tubulin is known to be a marker of stable microtubules in neurons, precise factors that regulate alpha-tubulin acetylation are, to date, largely unknown. Therefore, a genetic screen was employed in the nematode Caenorhabditis elegans that identified the Elongator complex as a possible regulator of alpha-tubulin acetylation.(More)
The TOCA family of F-BAR-containing proteins bind to and remodel lipid bilayers via their conserved F-BAR domains, and regulate actin dynamics via their N-Wasp binding SH3 domains. Thus, these proteins are predicted to play a pivotal role in coordinating membrane traffic with actin dynamics during cell migration and tissue morphogenesis. By combining(More)
The organization of the motor protein myosin into motile cellular structures requires precise temporal and spatial control. Caenorhabditis elegans UNC-45 facilitates this by functioning both as a chaperone and as a Hsp90 cochaperone for myosin during thick filament assembly. Consequently, mutations in C. elegans unc-45 result in paralyzed animals with(More)
The accumulation and deposition of amyloid beta (Aβ) peptide in extracellular dense plaques in the brain is a key phase in Alzheimer's disease (AD). Small oligomeric forms of Aβ are responsible for the toxicity and the early cognitive impairment observed in patients before the amyloid plaque deposits appear. It is essential for the development of an(More)
Transcription factors play key roles in cell fate specification and cell differentiation. Previously, we showed that the LIM homeodomain factor CEH-14 is expressed in the AFD neurons where it is required for thermotaxis behavior in Caenorhabditis elegans. Here, we show that ceh-14 is expressed in the phasmid sensory neurons, PHA and PHB, a number of neurons(More)
BACKGROUND NemaFootPrinter (Nematode Transcription Factor Scan Through Philogenetic Footprinting) is a web-based software for interactive identification of conserved, non-exonic DNA segments in the genomes of C. elegans and C. briggsae. It has been implemented according to the following project specifications:a) Automated identification of orthologous gene(More)

I like to thank all former and present members of the Baumeister lab for the great time and their support. Especially I like to thank our " worm " post-docs Dr. Bernard Lakowski and Dr. Giuseppe Cassata for their help with worms, for beer and their willingness and time to discuss any strange idea or result. I like to thank Stefan Eimer for his inexhaustible(More)
