這個基因編碼三個相關的絲素基因之一，特別是γ-絲素。這些絲素蛋白將肌動蛋白絲交聯成皮質細胞質中的正交網絡，并參與肌動蛋白細胞骨架膜蛋白的錨定。在絲狀蛋白中存在三個功能域：N-末端絲狀肌動蛋白結合結構域、C-末端自結合結構域和膜糖蛋白結合結構域。已經發現了兩個編碼不同亞型的轉錄變體。[由RefSeq提供，2008年7月]
This gene encodes one of three related filamin genes, specifically gamma filamin. These filamin proteins crosslink actin filaments into orthogonal networks in cortical cytoplasm and participate in the anchoring of membrane proteins for the actin cytoskeleton. Three functional domains exist in filamin: an N-terminal filamentous actin-binding domain, a C-terminal self-association domain, and a membrane glycoprotein-binding domain. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
