Function of nebulin
Did you know?
Other functions of nebulin, such as a role in cell signaling, remain uncertain. Nebulin has also been shown to regulate actin-myosin interactions by inhibiting ATPase activity in a calcium-calmodulin sensitive manner. Mutations in nebulin cause some cases of the autosomal recessive disorder nemaline myopathy. See more Nebulin is an actin-binding protein which is localized to the thin filament of the sarcomeres in skeletal muscle. Nebulin in humans is coded for by the gene NEB. It is a very large protein (600–900 kDa) and binds as many as … See more The structure of the SH3 domain of nebulin was determined by protein nuclear magnetic resonance spectroscopy.
