General annotation (Comments)

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. Ref.3

Subunit structure

May form homomeric filament after self-association or heteromeric filament after association with beta-tectorin.

Subcellular location

Cell membrane; Lipid-anchor › GPI-anchor; Extracellular side Probable. Secreted › extracellular space › extracellular matrix. Note: Found in the non-collagenous matrix of the tectorial membrane By similarity.

Tissue specificity

Expressed in the inner ear. Ref.1

Developmental stage

Apically located within the epithelium of the developing basilar papilla at days E5.5 to E8. As development proceeds, expression becomes restricted to the basal layer. In the utricle, alpha-tectorin is first expressed at E4.5. Ref.1

Domain

Zona pellucida domain may enable to form filaments.

Post-translational modification

At least 3 products of tectorin seem to exist: HMM, MMM and LMM. They may be generated by active processing or the result of proteolysis occurring between intrachain disulfide bonds.

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.

Sequence similarities

Contains 1 NIDO domain.

Contains 3 TIL (trypsin inhibitory-like) domains.

Contains 1 VWFC domain.

Contains 4 VWFD domains.

Contains 1 ZP domain.
