Bovine Gelsolin, GS ELI

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.

Plays a role in ciliogenesis (By similarity).
