CC -!- FUNCTION: Stimulates guanine exchange activity of SOS1. May play a role
CC in membrane ruffling and remodeling of the actin cytoskeleton (By
CC similarity). In the cochlea, is required for stereocilia maintenance in
CC adult hair cells (PubMed:23918390). {ECO:0000250|UniProtKB:Q9H6S3,
CC ECO:0000269|PubMed:23918390}.
CC -!- SUBUNIT: Interacts with ABI1. Part of a complex that contains SOS1,
CC ABI1 and EPS8L2. Associates with F-actin (By similarity).
CC {ECO:0000250|UniProtKB:Q9H6S3}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9H6S3}. Cell
CC projection, stereocilium {ECO:0000269|PubMed:23918390}. Note=Localizes
CC at the tips of the stereocilia of the inner and outer hair cells.
CC {ECO:0000269|PubMed:23918390}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q99K30-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q99K30-2; Sequence=VSP_019093, VSP_019094;
CC -!- TISSUE SPECIFICITY: Detected in fetal kidney, adrenal gland, salivary
CC gland, stomach, gut, cartilage and skin. Detected in adult ovary,
CC placenta, skin, adrenal gland, salivary gland, kidney, intestine and
CC stomach. Expressed at the tips of cochlear hair cells stereocilia
CC (PubMed:23918390). {ECO:0000269|PubMed:14565974,
CC ECO:0000269|PubMed:23918390}.
CC -!- DISRUPTION PHENOTYPE: Mutant animal have a progressive and severe
CC hearing loss at young adulthood (PubMed:23918390). The generation of
CC receptor potentials in hair cells at lower sound pressure is impaired,
CC which leads to a reduction in auditory nerve responses
CC (PubMed:23918390). {ECO:0000269|PubMed:23918390}.
CC -!- SIMILARITY: Belongs to the EPS8 family. {ECO:0000305}.
