Dnai2 Gene Summary [Rat]
Predicted to enable dynein heavy chain binding activity; dynein light chain binding activity; and microtubule motor activity. Predicted to be involved in cilium movement and outer dynein arm assembly. Predicted to act upstream of or within cilium assembly and determination of left/right symmetry. Predicted to be located in several cellular components, including dynein axonemal particle; external side of plasma membrane; and sperm flagellum. Predicted to be part of outer dynein arm. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia 9. Orthologous to human DNAI2 (dynein axonemal intermediate chain 2). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Dnai2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
