    • Relevance

      Gelsolin is a calcium regulated, actin modulating protein that binds to the plus (or barbed) ends of actin monomers or filaments, preventing monomer exchange (end blocking or capping). It can promote the assembly of monomers into filaments (nucleation) as well as sever filaments already formed. It plays a role in phosphoinositide mediated disassembly of actin filaments in Sertoli cell adhesion complexes; it may regulate sperm release and turnover of the blood testis barrier [RGD], and severs actin filaments in the presence of submicromolar calcium, thereby solating cytoplasmic actin gels. A calcium independent mechanism reverses the process. Northern blot analysis suggested that a single gene encodes both cell and plasma gelsolins. This protein may be unique in that it is made for both secretion and intracytoplasmic location.
