Tektorska membrana je apikalni vanćelijski matriks (aECM) unutrašnjeg uha , koji kontaktira stereocilijske snopove specijalizovane senzorne trepljaste ćelije . Zvuk inducira kretanje ovih ćelija u odnosu na membranu tektora, odbija od stereocilija i dovodi do fluktuacija u potencijalu membrane trepljaste ćelije, pretvarajući zvuk u električne signale. Alfa-tektorin je jedna od glavnih nekolagenskih komponenti tektorske membrane. Pokazalo se da su mutacije u TECTA genu odgovorne za autosomno dominantno nesindromsko oštećenje sluha i recesivni oblik senzorinervnu predjezičnu nesindromsku gluhoću .[ 7]
