8.A.186.  The Stereocilin, STRC, Protein (STRC) Family

STRC is essential to the formation of horizontal top connectors between outer hair cell stereocilia. It is an auditory receptor for cell stereocilium organization, is involved in cell to matrix adhesion as well as detection of mechanical stimuli for sensory perception of sound. AQP1 and STRC, and potentially TMEM255B, are serous (cystic) neoplasm (SCN) markers (Watase et al. 2021).
