DNAI2

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

Function

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

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