Dnah2 Gene Summary [Rat]
Predicted to enable dynein intermediate chain binding activity; dynein light intermediate chain binding activity; and minus-end-directed microtubule motor activity. Predicted to be involved in cilium movement involved in cell motility and inner dynein arm assembly. Predicted to be located in sperm flagellum. Predicted to be part of inner dynein arm. Predicted to be active in 9+2 motile cilium and axoneme. Human ortholog(s) of this gene implicated in spermatogenic failure 45. Orthologous to human DNAH2 (dynein axonemal heavy chain 2).

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 Dnah2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
