MYO18B (Myosin XVIIIB) is a Protein Coding gene. Diseases associated with MYO18B include Klippel-Feil Syndrome 4, Autosomal Recessive, With Myopathy And Facial Dysmorphism and Klippel-Feil Syndrome 4. Among its related pathways are Sertoli-Sertoli Cell Junction Dynamics and Actin Nucleation by ARP-WASP Complex. The protein encoded by MYO18B may regulate muscle-specific genes when in the nucleus and may influence intracellular trafficking when in the cytoplasm. The encoded protein functions as a homodimer and may interact with F actin. Mutations in MYO18B are associated with lung cancer.
