Whrn Gene Summary [Rat]
Enables protein domain specific binding activity. Predicted to be involved in several processes, including detection of mechanical stimulus involved in sensory perception of sound; nervous system development; and paranodal junction maintenance. Predicted to act upstream of or within establishment of localization in cell; establishment of protein localization; and positive regulation of gene expression. Located in several cellular components, including dendrite; photoreceptor connecting cilium; and stereocilium tip. Human ortholog(s) of this gene implicated in Usher syndrome type 2D; autosomal recessive nonsyndromic deafness 31; and sensorineural hearing loss. Orthologous to human WHRN (whirlin).

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