Here we characterize [MEC-15][1], an F-box protein with WD repeats, which is required for the development and function of Caenorhabditis elegans touch receptor neurons (TRNs). Selective protein degradation is a key regulator of neuronal development and synaptogenesis. mec-4d, mec-4, and mec-6 have been described previously (Huang and Chalfie 1994; Driscoll and Chalfie 1991; Chalfie and Au 1989). TCA scholar Gizem Orbey added yet another high profile interview to her already impressive resume as a science journalist with an interview featuring Nobel Laureate Martin Chalfie.

If you do not receive an email within 10 minutes, your email address may not be registered, Molecular chaperones often work collaboratively with the ubiquitination-proteasome system (UPS) to facilitate the degradation of misfolded proteins, which typically safeguards cellular differentiation and protects cells from stress. WormBook (Author Webpage) is an open-access, online collection of original, peer-reviewed chapters on the biology of Caenorhabditis elegans and related nematodes.Since WormBook was launched in June 2005 with 12 chapters, it has grown to over 100 chapters, covering nearly every aspect of C.elegans research, from Cell Biology and Neurobiology to Evolution and Ecology. In the nematode In the past decade there has been an increasing awareness of the critical role that selective proteolytic degradation plays in regulating a diverse set of steps in neuronal differentiation and function (In this article, we describe the molecular and phenotypic characterization of Plasmid NM1234 was created in two steps from plasmid NM1023 (Plasmid TU#875 was generated using the GFP expression vector pPD95.75 (a gift from Andy Fire, Stanford University, Stanford, CA; Fire Laboratory Vector kit; Whole-mount immunochemistry was carried out as described previously (Touch sensitivity of worms was tested by stroking the animals with an eyebrow hair attached to a toothpick (For fluorescence microscopy, animals were anesthetized using 0.3 Nerve rings of young, gravid adults (4 days after hatching if grown at 20°, 3 days if grown at 25°, 6 days if grown at 15°) were photographed at ×63 magnification and the same exposure.
