The methionine sulfoxide reductase B3 gene (MsrB3), a protein repair enzyme, has been implicated in large scale stereocilia bundle degeneration, as well as many other factors such as gestational age and tolerance to cold environments in plants. Although the exact process of pathogenesis is unknown, it seems to be related to apoptotic cell death. A study based on splicing morpholinos to down-regulate MsrB3 expression in zebrafish showed shorter, thinner, and more crowded cilia, as well as small, misplaced otoliths. Several stereocilia also underwent apoptosis. Injection with wild-type MsrB3 mRNA rescued auditory deficits, suggesting MsrB3 helps prevent apoptosis.

Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (HA722410) at 1/1,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature.
