Abstract excerpt
The deafwaddler mutant in mice was the first spontaneous mutant discovered in the plasma membrane Ca(2+) pump (PMCA) [Street, V.A. et al., 1998, Nat. Genet. 19, 390-394]. A nucleotide substitution in deafwaddler results in a Gly to Ser transition at amino acid 283 in the small cytoplasmic loop of PMCA isoform 2 (PMCA2). PMCA2 is abundant in the stereocilia of auditory and vestibular hair cells, neurons of the...
