Hypothesis
The microtubules may provide trafficking routes for the polarity proteins during photoreceptor morphogenesis.
Conclusion
Kinesin heavy chain is essential for microtubule structure and Crb localization during rhabdomere elongation in Drosophila photoreceptors.
Supporting Evidence
- Kinesin heavy chain is essential for the localization of Crb in developing photoreceptors.
- khc mutants showed progressive defects in Crb localization along the distal-proximal axis.
- Overexpression of khc disrupted the apical membrane domain and stabilized microtubules.
Takeaway
This study found that a protein called Kinesin helps move important molecules to the right places in developing eyes of fruit flies, which is crucial for their proper growth.
Methodology
The study examined Crb localization in developing photoreceptors of khc mutants and analyzed genetic interactions between crb and khc.
Limitations
The genetic interaction data is preliminary and not conclusive.
