Gelsolin (GS) Antibody – Rabbit Polyclonal

Gelsolin: 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. Its expression is significantly decreased in many tumors and transformed cell lines. Gelsolin and other proteins including E-cadherin, BRCA, p21WAF, HoxA5, and retinoic acid receptor II are regulated by epigenetic changes in breast cancers. Gelsolin helps mediate the ability of HDAC inhibitors to protect neurons from oxygen/glucose deprivation. Two human isoforms are produced by alternative initiation.
