UMass Amherst cell biologists identify new protein key to asymmetric cell division
Date:11/8/2012

now we have identified this new player with the ability to specifically regulate this pulling very locally. If there's high She1 concentration on one side of the spindle, dynein can only pull from the other side, thus specifying the direction of the pulling."

There is no counterpart to She1 found in common yeast yet known in humans, but Lee and colleagues expect a similar protein will be discovered that regulates and directs dynein's pulling in asymmetric cell division.
