dc.description.abstract | <p>We have used a yeast two-hybrid screen to identify lamin Dm0 as an interaction partner for the nuclear JIL-1 kinase. This molecular interaction was confirmed by GST-fusion protein pull-down assays and by co-immunoprecipitation experiments. Using deletion construct analysis we show that a predicted globular domain of the basic region of the COOH-terminal domain of JIL-1 was sufficient for mediating the molecular interactions with lamin Dm0. A reciprocal analysis with truncated lamin Dm0 constructs showed that the interaction with JIL-1 required sequences in the tail domain of lamin Dm0 that include the Ig-like fold. Further support for a molecular interaction between JIL-1 and lamin Dm0 in vivo was provided by genetic interaction assays. We show that nuclear positioning and lamina morphology were abnormal in <em>JIL-1</em> mutant egg chambers. The most common phenotypes observed were abnormal nurse cell nuclear lamina protrusions through the ring canals near the oocyte, as well as dispersed and mislocalized lamin throughout the egg chamber. These phenotypes were completely rescued by a full-length <em>JIL-1</em> transgenic construct. Thus, our results suggest that the JIL-1 kinase is required to maintain nuclear morphology and integrity of nurse cells during oogenesis and that this function may be linked to molecular interactions with lamin Dm0.</p> | |
