Go Annotations as Summary Text (Tabular View) (GO Graph)

GO curators for mouse genes have assigned the following annotations to the gene product of Whrn. (This text reflects annotations as of Tuesday, May 26, 2015.)
Summary from NCBI RefSeq

This gene encodes a protein required for elongation and actin polymerization in the hair cell stereocilia. The encoded protein is localized to the cytoplasm and co-localizes with the growing end of actin filaments. Mutations in this gene have been linked to deafness. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2013]
