Filamin

Crystal structure of Human Filamin A complex with phosphate, 3hop

• Filamin A (FLNA) has an actin-binding domain (ABD). It crosslinks actin filaments and participates in anchoring of membrane proteins.
  
• Filamin B (FLNB) is a human cytoplasmic protein which functions similarly to FLNA and guides proper skeletal development.
  
• Filamin C (FLNC) is functionally similar and contains 3 domains: the N-terminal ABD, the C-terminal dimerization domain (DD) and a membrane glycoprotein-binding domain.
