The change in gene expression induced by desiccation in the semiarid, entomopathogenic nematode Steinernema feltiae IS-6, includes induction of transcription of a nucleosome assembly protein, NAP1 homolog, and of casein kinase 2 (CK2) genes. Therefore, one of the events during the dehydration response of S. feltiae IS-6 may be transcriptional activation by S. feltiae IS-6 NAP1 homolog (Sf-Nap1), which is regulated by 5. feltiae IS-6 CK2 (Sf-CK2). This regulation necessitates physical interaction between the Sf-Nap1 and Sf-CK2 proteins. In the present study we used yeast 2-hybrid analysis to demonstrate physical interaction between the 2 proteins, thus confirming the involvement of a protein interaction-based step in the desiccation response mechanism of S. feltiae IS-6. © American Society of Parasitologists 2005.
