Function

Outher dynein arm intermediate chain protein. D I and DNAI2 form a complex essential for the stability of both proteins during early stages of outer dynein arms assembly (29113992). Essential for axonemal assembly of the ODA heavy chains DNAH5 and DNAH9 (18950741). Required for ODA formation in Kupffer's Vesicle cilia and controls the stablishment of left-right doby axis and kidney formation through regulation of ciliary motility.(20709053, 20707998)
