Summary

TECTB (tectorin beta, HGNC:11721) is a protein-coding gene on chromosome 10q25.2, encoding Beta-tectorin (Q96PL2). One of the major non-collagenous components of the tectorial membrane.

This gene encodes a non-collagenous glycoprotein component of the tectorial membrane, which covers the auditory hair cells in the cochlea of the inner ear. A similar protein in mouse functions in low-frequency hearing.

Function. One of the major non-collagenous components of the tectorial membrane. The tectorial membrane is an extracellular matrix of the inner ear that covers the neuroepithelium of the cochlea and contacts the stereocilia bundles of specialized sensory hair cells. Sound induces movement of these hair cells relative to the tectorial membrane, deflects the stereocilia and leads to fluctuations in hair-cell membrane potential, transducing sound into electrical signals.

Subunit / interactions. May form homomeric filament after self-association or heteromeric filament after association with alpha-tectorin. Interacts with CEACAM16.

Subcellular location. Cell membrane. Secreted. Extracellular space. Extracellular matrix.

Post-translational modifications. The presence of a hydrophobic C-terminus preceded by a potential cleavage site strongly suggests that tectorins are synthesized as glycosylphosphatidylinositol-linked, membrane-bound precursors. Tectorins are targeted to the apical surface of the inner ear epithelia by the lipid and proteolytically released into the extracellular compartment.

Domain organisation. Zona pellucida domain may enable to form filaments.
