suggest a mechanism for Sisyphus (the Drosophila myosin XV homolog) in which it maintains a balance between actin and microtubule cytoskeleton components
Myosin 15 (show MYH15 Antibodies) isoforms can navigate between functionally distinct classes of stereocilia, and are independently required to assemble and then maintain the intricate hair bundle architecture.
myo15-subfragment 1 is a barbed-end-directed motor that moves actin filaments in a gliding assay using a power stroke of 7.9 nm. Myo15-S1 was rate limited by transit through strongly actin-bound states, similar to other processive myosin motors.
It was concluded that MyoXVa, whirlin, and Eps8 are integral components of the stereocilia tip complex, where Eps8 is a central actin-regulatory element for elongation of the stereocilia actin core.
endogenous myosin XVa localizes to the tips of the stereocilia of the cochlear and vestibular hair cells
myosin-XVa is a motor protein (show MYO7A Antibodies) that, in vivo, interacts with the third PDZ domain (show INADL Antibodies) of whirlin (show DFNB31 Antibodies) through its carboxy-terminal PDZ (show INADL Antibodies)-ligand. Myosin-XVa then delivers whirlin (show DFNB31 Antibodies) to the tips of stereocilia.
This comparison revealed that the absence of functional myosin-XVa does not disrupt adaptation of the mechanotransduction current during sustained bundle deflection.
The morphology of cochlear hair cell stereocilia in double mutants reflects a dominance of the more severe Myo15 (sh2/sh2) phenotype over the Whrn (wi/wi (show DFNB31 Antibodies)) phenotype.
The Ca(2 (show CA2 Antibodies)+) sensitivity of the mechanotransduction channels and the fast adaptation require a structural environment that is dependent on myosin-XVa and is disrupted in Myo15(sh2/sh2) inner hair cells, but not in Myo15(sh2/sh2) outer hair cells.
Mutations in exon 2 of MYO15A may cause a less severe phenotype, facilitating the rapid identification of mutations in exon 2 among the 66 exons when linkage of less severe hearing loss to DFNB3 is detected
MYO15A mutations that affect domains other than the N-terminal domain, lead to profound sensorineural hearing loss throughout all frequencies.
MYO15A Mutation is associated with Autosomal Recessive Nonsyndromic Hearing Loss.
Mutations in the MYO15A gene are a notable cause of nonsyndromic hearing loss.
Data indicate nine novel mutations in the genes encoding myosin VI (show MYO6 Antibodies), myosin VIIA (show MYO7A Antibodies) and myosin XVA in hearing-impaired individuals from Israeli Jewish and Palestinian Arab families.
MYO15A c.IVS25+3G>A and c.8375 T>C (p.V2792A) as the autosomal recessive hearing loss-causing mutations
study found two novel compound heterozygous mutations of MYO15A and 13 nonsynonymous variants in the coding exons of MYO15A from Korean exomes in families with autosomal recessive nonsyndromic hearing loss
sequencing of the MYO15A gene led to identification of 7 previously unreported mutations, including 4 missense mutations, 1 nonsense mutation, and 2 deletions in different regions of the myosin-XV protein
the second exon of MYO15A from the DNA of all affected individuals ofHEARING LOSS IN A family revealed a duplication of Cytosine in a stretch of seven repetitive C nucleotides (c.1185dupC).
Estimation of the prevalence of homozygous MYO15A mutations in autosomal recessive nonsyndromic deafness in Turkey as 0.062 (95% confidence interval is 0.020-0.105).
Myosins are actin-based motor molecules with ATPase activity. Unconventional myosins serve in intracellular movements. Their highly divergent tails are presumed to bind to membranous compartments, which would be moved relative to actin filaments (By similarity). Required for the arrangement of stereocilia in mature hair bundles.
