Pondering aquaporins
Yongho Park has posted two pictures of aquaporin molecules — first identified by Duke’s Peter Agre — that look rather like green crayons wrapped in yarn. One of them readily joins a lipid raft on the bilayer membrane, the other one doesn’t.
Yongho says you can figure it out yourself “if you keep staring at the images,” which we’re guessing he has during his time in the Thomas McIntosh lab.
