Microtubule-associated serine/threonine-protein kinase 2 (Mast2)

Appears to link the dystrophin/utrophin network with microtubule filaments through the syntrophins. Phosphorylation of DMD or UTRN may modulate their affinities for associated proteins.

Functions in a multi-protein complicated in spermatid maturation. Regulates lipopolysaccharide-induced IL-12 synthesis in macrophages by forming a complex with TRAF6, resulting in the inhibition of TRAF6 NF-kappa-B activation.
