PHYSIOLOGY

Definition A type of caveolae-mediated vesicular trafficking, in which caveolae mediate the uptake of small solutes measuring less than 1 kDa–classically folate and other vitamins–by pinching off, but remaining associated with the plasma membrane. The small solutes then passively diffuse into the cytoplasm. The molecular machinery involved in caveolar fission/fusion is identical to that used for other vesicular transport processes, as all require dynamin, VAMP, SNAP-25, SNARE complex, and GTP hydrolysis.
