Abstract

Caveolae are specialized small plasma-membrane invaginations that play crucial cellular functions. Two essential protein families are required for caveola formation: membrane caveolin proteins and cytoplasmic cavin proteins. Each family includes members with specific tissue distribution, and their expression is altered under. physiological and pathological conditions, implying highly specialized functions. Cavins not only stabilize caveolae, but modulate their morphology and functions as well. Before association with the plasma membrane, cavins form homo- and hetero-oligomers with strikingly strict stoichiometry in the cytosol. At the plasma membrane, they provide an outer peripheral cytosolic layer, necessary for caveola stability. Interestingly, upon stimulation, cavins can be released from caveolae into the cytoplasm in distinct subcomplexes, providing a rapid dynamic link between caveolae and cellular organelles including the nucleus. In this review, we detail the biology of cavins, their structural and functional roles, and their implication in pathophysiology.
