UniProt functional annotation for Q495M9



	UniProt functional annotation for Q495M9

UniProt code: Q495M9.

Organism: Homo sapiens (Human).

Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.

Function: Required for normal development and maintenance of cochlear hair cell bundles. Anchoring/scaffolding protein that is a part of the functional network formed by USH1C, USH1G, CDH23 and MYO7A that mediates mechanotransduction in cochlear hair cells. Required for normal hearing. {ECO:0000269|PubMed:21709241}.

Subunit: Interacts with CDH23 and PCDH15; these interactions may recruit USH1G to the plasma membrane (By similarity). Interacts with USH1C (via the first PDZ domain) and with USH1G. Interacts with PDZD7. Interacts with MYO7A. Part of a complex composed of USH1C, USH1G and MYO7A. {ECO:0000250, ECO:0000269|PubMed:12588794, ECO:0000269|PubMed:19028668, ECO:0000269|PubMed:20142502, ECO:0000269|PubMed:21311020, ECO:0000269|PubMed:21709241}.

Subcellular location: Cytoplasm, cytosol. Cytoplasm, cytoskeleton. Cell membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}. Note=Detected at the tip of cochlear hair cell stereocilia. Recruited to the cell membrane via interaction with CDH23 or PCDH15 (By similarity). {ECO:0000250}.

Tissue specificity: Expressed in vestibule of the inner ear, eye and small intestine. {ECO:0000269|PubMed:12588794}.

Disease: Usher syndrome 1G (USH1G) [MIM:606943]: USH is a genetically heterogeneous condition characterized by the association of retinitis pigmentosa with sensorineural deafness. Age at onset and differences in auditory and vestibular function distinguish Usher syndrome type 1 (USH1), Usher syndrome type 2 (USH2) and Usher syndrome type 3 (USH3). USH1 is characterized by profound congenital sensorineural deafness, absent vestibular function and prepubertal onset of progressive retinitis pigmentosa leading to blindness. {ECO:0000269|PubMed:12588794, ECO:0000269|PubMed:16283141, ECO:0000269|PubMed:20142502}. Note=The disease is caused by variants affecting the gene represented in this entry.

Disease: Note=The first cases with non-syndromic sensorineural hearing loss based on mutations in USH1G. The hearing loss has an onset during early childhood, is progressive, and has a downsloping audiogram configuration. Ophthalmic and vestibular abnormalities are absent. {ECO:0000269|PubMed:25255398}.
