== Function ==
 +
* [[Filamin]] '''A (FLNA)''' has an actin-binding domain (ABD). It crosslinks actin filaments and participates in anchoring of membrane proteins<ref>PMID:19773341</ref>.<br />
 +
* '''Filamin B (FLNB)''' is a human cytoplasmic protein which functions similarly to FLNA and guides proper skeletal development<ref>PMID:19505475</ref>.<br />
 +
* '''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<ref>PMID:11336782</ref>.<br />
 +
For more details on filamin C see [[Group:MUZIC:FilaminC]].
 +
== Disease ==
-
 
+
Mutations in FLNA cause frontometaphyseal dysplasia, intestinal pseudo-obstruction, Melnick-Needles syndrome, otopalatodigital syndrome and periventricular heterotopia. Mutations in FLNAB cause boomerang dysplasia.
