The motion of motor proteins on biopolymers is important for diverse biological processes. Actin, microtubules, and nucleic acids can serve as one-dimensional tracks on which motor proteins move.

The leading cause of miscarriage is that human eggs are surprisingly bad at managing the number of chromosomes in them. But now, researchers at the Max Planck Institute have identified a motor protein ...

Human eggs often contain the wrong number of chromosomes, leading to miscarriages and infertility. A research team has discovered that human eggs are missing an important protein, which acts as a ...

Then the motors use this walking motion to push the microtubules around to arrange them into the spindle structure." Before Wignall's new study, researchers believed two motor proteins (dynein and ...

When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells. The spindle is the machinery behind that process: It latches onto ...

In a new Current Biology study, CU Boulder Physics Professor Meredith Betterton and her team explored a key motor protein in cells called kinesin-5, which helps organize the cell division machinery, ...

What bones are to bodies, the cytoskeleton is to cells. The cytoskeleton maintains cellular structure, builds appendages like flagella and, together with motor proteins, powers cellular movement, ...

Most of us will probably be able to recall at least vaguely that a molecule called ATP is essential for making our bodies move, but this molecule is only a small part of a much larger system. Although ...

Scientists have a solid understanding of what makes up spindles — the cellular machinery that separates chromosomes — but are less certain about how the building blocks of spindles, called ...
