<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

Pore-forming subunit of a voltage-gated ion channel required for sensory perception of sweet, bitter and umami tastes. Specifically present in type II taste bud cells, where it plays a central role in sweet, bitter and umami taste perception by inducing ATP release from the cell, ATP acting as a neurotransmitter to activate afferent neural gustatory pathways. Acts both as a voltage-gated and calcium-activated ion channel: mediates neuronal excitability in response to changes in extracellular Ca2+ concentration. Has poor ion selectivity and forms a wide pore (around 14 Angstroms) that mediates permeation of Ca2+, Na+ and K+, as well as permeation of monovalent anions. Acts as an activator of the ERK1 and ERK2 cascade. Triggers endoplasmic reticulum stress by reducing the calcium content of the endoplasmic reticulum. May indirectly control amyloid precursor protein (APP) proteolysis and aggregated amyloid-beta (Abeta) peptides levels in a Ca2+ dependent manner.2 Publications

Impaired perceptions of sweet, bitter and umami compounds. Mice are viable and fertile, with no visible morphological abnormalities in their taste buds or any altered expression of taste-related marker genes. They do however display a loss of both preference for sweet and umami compounds and for avoidance of bitter compounds. Perceptions of sour and salty tastes are unaffected. Reduced voltage-gated currents in type II cells and taste-evoked ATP release from taste buds without affecting the excitability of taste cells by taste stimuli. Elderly males and females do not show defects in spatial learning and memory retrieving.2 Publications
