Filamin B, beta (FLNB), also known as Filamin B, beta (actin binding protein 278), is a cytoplasmic protein which in humans is encoded by the FLNB gene.

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.[1]

Mutations in the FLNB gene are involved in several lethal bone dysplasias, including boomerang dysplasia and atelosteogenesis type I.[2][3][4]


Interactions

FLNB has been shown to interact with GP1BA,[5] Filamin,[6] FBLIM1,[7] PSEN1,[8] CD29[9] and PSEN2.[8]
