Protein: Taperin (A2AI08)
Organism: Mus musculus (Mouse)
Function: Not known
Subcellular location: Cell projection, stereocilium {ECO:0000269|PubMed:20170899, ECO:0000269|PubMed:24285636, ECO:0000269|PubMed:30159668, ECO:0000269|PubMed:30380417, ECO:0000269|PubMed:35752427, ECO:0000269|PubMed:37952086}. Cell projection, microvillus {ECO:0000269|PubMed:24285636}. Nucleus, nucleoplasm {ECO:0000250|UniProtKB:Q4KMQ1}. Cytoplasm {ECO:0000250|UniProtKB:Q4KMQ1}. Note=Localized prominently at the basal taper region of hair cell stereocilia (PubMed:20170899, PubMed:30159668, PubMed:30380417, PubMed:37952086). Forms organized ring-like structures with diameters ranging from 150 to 200 nm in the stereocilium taper region (PubMed:37952086). Detected in microvilli of inner hair cell supporting cells (PubMed:24285636). Predominantly nuclear in non-stereocilium cells but can shuttle between the nucleus and the cytoplasm (By similarity). {ECO:0000250|UniProtKB:Q4KMQ1, ECO:0000269|PubMed:20170899, ECO:0000269|PubMed:24285636, ECO:0000269|PubMed:30159668, ECO:0000269|PubMed:30380417, ECO:0000269|PubMed:37952086}.
