..Lethality was attributed to diverse cellular and developmental defects, such as organ formation and patterning defects. These data suggest that new genes frequently and rapidly evolve essential functions and participate in development. ..

..We propose that maternal MAMO activates downstream genes to promote specialized morphological changes of both female meiotic chromosomes and the sperm nucleus, which are critical in zygote formation. ..

..Here, we report the identification and characterization of the Hip-interacting protein Umbrea. We found that Umbrea interacts directly with Hip, HP1 and HOAP in vitro...

..We conclude that evolution of the hybrid lethality properties of Lhr between D. melanogaster and D. simulans did not involve extensive loss or gain of functions associated with protein interactions or localization to heterochromatin...

..The birth and death of HP1 genes follows a "revolving door" pattern, where new HP1s appear to replace old HP1s. Here, we address alternative evolutionary models that drive this constant innovation. ..

..As a result, chromatin binding proteins may not be able to interact with chromosomes from another species in a hybrid, causing hybrid sterility and inviability. ..
