== Disease ==
 +
[https://www.uniprot.org/uniprot/GELS_HUMAN GELS_HUMAN] Defects in GSN are the cause of amyloidosis type 5 (AMYL5) [MIM:[https://omim.org/entry/105120 105120]; also known as familial amyloidosis Finnish type. AMYL5 is a hereditary generalized amyloidosis due to gelsolin amyloid deposition. It is typically characterized by cranial neuropathy and lattice corneal dystrophy. Most patients have modest involvement of internal organs, but severe systemic disease can develop in some individuals causing peripheral polyneuropathy, amyloid cardiomyopathy, and nephrotic syndrome leading to renal failure.<ref>PMID:2157434</ref> <ref>PMID:2153578</ref> <ref>PMID:2176481</ref> <ref>PMID:1338910</ref>

== Function ==
 +
[https://www.uniprot.org/uniprot/GELS_HUMAN GELS_HUMAN] 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.<ref>PMID:20393563</ref>

== Publication Abstract from PubMed ==
 +
Gelsolin requires activation to carry out its severing and capping activities on F-actin. Here, we present the structure of the isolated C-terminal half of gelsolin (G4-G6) at 2.0 A resolution in the presence of Ca(2+) ions. This structure completes a triptych of the states of activation of G4-G6 that illuminates its role in the function of gelsolin. Activated G4-G6 displays an open conformation, with the actin-binding site on G4 fully exposed and all three type-2 Ca(2+) sites occupied. Neither actin nor the type-l Ca(2+), which normally is sandwiched between actin and G4, is required to achieve this conformation.
