Filamin

Filamins are a class of proteins that hold two actin filaments at large angles.[1] Filamin protein in mammals is made up of an actin-binding domain at its N-terminus that is followed by 24 immunoglobulin-like repeat modules of roughly 95 amino acids. There are two hinge regions; between repeats 15-16 and 23-24. Filamin gets cleaved at these hinge regions to generate smaller fragments of the protein. Filamin has two actin-binding sites with a V-linkage between them, so that it cross-links actin filaments into a network with the filaments orientated almost at right angles to one another.[2]

Filamin proteins include:

Over-expression of FLNA stops the regeneration of bladder carcinoma (BC) cells, by inhibiting the cell cycle and inducing apoptosis of BC cells.[3] FLNA has also been shown to reduce the mobility and invasion abilities of BC cells.[3]
