ODAD2

Chr 10AR

outer dynein arm docking complex subunit 2

Also known as: ARMC4, CILD23, gudu

The protein is a component of the outer dynein arm-docking complex that mediates outer dynein arm binding to ciliary microtubules, essential for normal ciliary motility. Mutations cause primary ciliary dyskinesia characterized by chronic respiratory disease and laterality defects due to defective ciliary beating. Inheritance is autosomal recessive.
