Brain Clathrin: A Study of Its Properties
In 1968, Puszkin, Berl and coworkers reported the presence of contractile proteins in whole brain (1). Subsequent work showed the presence of contractile proteins in nerve-endings (2,3,4). The properties of various contractile proteins found in brain tissue resembled, to a large extent, those from muscle tissue (2,4). As a result, it was proposed that contractile activities are involved in neurotransmitter release (5). With the advantage of sodium dodecyl sulfate polyacrylamide gel electrophoresis as a procedure for distinguishing and comparing the size of various proteins, many researchers working with other tissues or cells began to report the presence and involvement of contractile proteins in motility-related cell functions (6).
