Human Myosin-IXb (MYO9B) ELISA Kit

MYO9B encodes a member of the myosin family of actin-based molecular motor heavy chain proteins. Myosin-IXb represents an unconventional myosin; it should not be confused with the conventional non-muscle myosin-9 (MYH9). Myosin-IXb has four IQ motifs located in the neck domain that bind calmodulin, which serves as a light chain. Myosin-IXb complex has a single-headed structure and exhibits processive movement on actin filaments toward the minus-end. Myosin-IXb also has rho-GTPase activity. Polymorphisms in MYO9B are associated with celiac disease and ulcerative colitis susceptibility. Multiple transcript variants encoding different isoforms have been found for MYO9B.
