Abstract/Description
-
The dauer larva is an alternate larval stage which allows the nematode C. elegans to survive environmestress during development. Dauer formation requires autophagy, a cellular process responsible for degrading and recycling cytoplasmic components. I investigated the role of a spinster orthiolog, C13C4.5, by examining the effects of C13C4.5 loss-of-function and by generating a transgenic strain which expressed a C13C4.5::GFP fusion protein. Under normal conditions C13C4.5::GFP is expressed...
Show moreThe dauer larva is an alternate larval stage which allows the nematode C. elegans to survive environmestress during development. Dauer formation requires autophagy, a cellular process responsible for degrading and recycling cytoplasmic components. I investigated the role of a spinster orthiolog, C13C4.5, by examining the effects of C13C4.5 loss-of-function and by generating a transgenic strain which expressed a C13C4.5::GFP fusion protein. Under normal conditions C13C4.5::GFP is expressed diffusely in the intestine, but under autophagy-promoting conditions the expression pattern becomes more punctate. This is consistent with localization of C13C4.5 to autophagolysomoes during autophagy, as has been shown for spinster in D. melanogaster. Loss of C13C4.5 function in a dauer-constitutive mutant resulted in a reduction in the proportion of animals entering into the dauer stage. Together these data suggest that C13C4.5 is involved in dauer formation and the autophagy pathway.
