FLNB regulates intracellular communication and signalling by cross-linking the protein actin to allow direct communication between the cell membrane and cytoskeletal network, to control and guide proper skeletal development.[5]

Mutations in the FLNB gene are involved in several lethal bone dysplasias, including boomerang dysplasia and atelosteogenesis type I.[6][7][8]

Interactions

FLNB has been shown to interact with GP1BA,[9] Filamin,[10] FBLIM1,[11] PSEN1,[12] CD29[13] and PSEN2.[12]
