Kinesin-4 KIF21B combines a processive motor activity with two non-motor microtubule-binding domains and an autoregulatory region to induce pausing of microtubule plus ends.

Overexpression of hAC8 engages complex, coordinate adaptation 'circuity' that has evolved in mammalian cells to defend against stress that threatens health or life, and may be important for proper healing in disease states such as heart infarction or failure.

This review serves as a gateway to experimental, conceptual, and quantitative themes of cytoplasmic incompatibility (CI) and outlines significant gaps in the understanding of CI's mechanism that are ripe for investigation.

A novel regulatory model for the diversification of cardiac cell subpopulations in Drosophila is established by linking epidermal growth factor signaling with differential activities of key transcription factors.
