Dynein intermediate chain 2, axonemal, also known as axonemal dynein intermediate chain 2, is a protein that in humans is encoded by the DNAI2 gene.[5][6]


The protein encoded by this gene belongs to the dynein intermediate chain family, and is part of the dynein complex of respiratory cilia and sperm flagella.[5]

Clinical significance[edit]

Mutations in the DNAI2 gene are associated with primary ciliary dyskinesia.[7]
