CC   -!- FUNCTION: Multifunctional actin-bundling protein. Plays a major role in
CC       regulating the organization, dimension, dynamics and signaling
CC       capacities of the actin filament-rich microvilli in the mechanosensory
CC       and chemosensory cells (PubMed:29572253). Required for the assembly and
CC       stabilization of the stereociliary parallel actin bundles. Plays a
CC       crucial role in the formation and maintenance of inner ear hair cell
CC       stereocilia (By similarity). Involved in the elongation of actin in
CC       stereocilia (PubMed:29572253). In extrastriolar hair cells, required
CC       for targeting MYO3B to stereocilia tips, and for regulation of
CC       stereocilia diameter and staircase formation.
CC       {ECO:0000250|UniProtKB:Q9ET47, ECO:0000269|PubMed:29572253}.
CC   -!- SUBUNIT: Monomer. Binds F-actin in a Ca(2+)-resistant fashion.
CC       Interacts (via N-terminus) with BAIAP2 (via SH3-domain). Interacts with
CC       PFN2. Interacts with MYO3A (via C-terminus). Interacts with MYO3B (via
CC       C-terminus). {ECO:0000250|UniProtKB:Q9ET47}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton
CC       {ECO:0000250|UniProtKB:Q9ET47}. Cell projection, stereocilium
CC       {ECO:0000269|PubMed:29572253}. Cell projection, microvillus
CC       {ECO:0000269|PubMed:29572253}.

CC   -!- DOMAIN: The WH2-domain binds actin monomer and mediates actin bundle
CC       assembly. {ECO:0000250|UniProtKB:Q9ET47}.
CC   -!- DISEASE: Deafness, autosomal recessive, 36, with or without vestibular
CC       involvement (DFNB36) [MIM:609006]: A form of non-syndromic
CC       sensorineural hearing loss. Sensorineural deafness results from damage
CC       to the neural receptors of the inner ear, the nerve pathways to the
CC       brain, or the area of the brain that receives sound information. DFNB36
CC       is characterized by prelingual, profound hearing loss, and vestibular
CC       areflexia in some patients. {ECO:0000269|PubMed:15286153,
CC       ECO:0000269|PubMed:15930085, ECO:0000269|PubMed:28281779}. Note=The
CC       disease is caused by variants affecting the gene represented in this
CC       entry.
CC   -!- DISEASE: Usher syndrome 1M (USH1M) [MIM:618632]: A form of Usher
CC       syndrome, a genetically heterogeneous condition characterized by the
CC       association of retinitis pigmentosa with sensorineural deafness. Age at
CC       onset and differences in auditory and vestibular function distinguish
CC       Usher syndrome type 1 (USH1), Usher syndrome type 2 (USH2) and Usher
CC       syndrome type 3 (USH3). USH1M is an autosomal recessive disease
CC       characterized by prelingual sensorineural hearing loss, vestibular
CC       dysfunction, night blindness, and progressive impairment of vision.
CC       {ECO:0000269|PubMed:29572253}. Note=The disease may be caused by
CC       variants affecting the gene represented in this entry.
