MYO9B antibodies target myosin IXB (MYO9B), a motor protein belonging to the myosin superfamily involved in cellular movement, cytoskeletal organization, and immune regulation. MYO9B is a single-headed, processive myosin with a unique RhoGAP domain, enabling it to regulate Rho GTPase signaling and modulate actin dynamics. It plays a critical role in maintaining epithelial barrier integrity, particularly in the gastrointestinal tract, by coordinating cell-cell junctions and cell migration.
Research links MYO9B deficiency or dysfunction to autoimmune and inflammatory disorders, notably celiac disease, inflammatory bowel disease (IBD), and systemic lupus erythematosus (SLE). Genetic variants in MYO9B are associated with increased intestinal permeability, triggering aberrant immune responses to environmental antigens. MYO9B antibodies, detected in autoimmune contexts, may serve as biomarkers for disease susceptibility or activity, though their pathogenic role remains under investigation.
In diagnostics, MYO9B antibodies are studied using ELISA, immunofluorescence, or Western blot, often in research exploring molecular mechanisms of autoimmunity. Their presence may reflect disrupted epithelial homeostasis or cross-reactivity due to molecular mimicry. Further studies aim to clarify whether these antibodies contribute directly to tissue damage or are secondary to inflammation. Understanding MYO9B biology and its antibodies holds promise for unraveling autoimmune pathogenesis and developing targeted therapies.
