Rabbit anti-Human TRPA1 Polyclonal Antibody

Uniprot Id

O75762

Target Species

Human

Target Name

TRPA1

Target Full Name

Transient receptor potential cation channel subfamily A member 1

Target Function

Receptor-activated non-selective cation channel involved in pain detection and possibly also in cold perception, oxygen concentration perception, cough, itch, and inner ear function. Shows 8-fold preference for divalent over monovalent cations. Has a central role in the pain response to endogenous inflammatory mediators and to a diverse array of irritants, such as allylthiocyanate (AITC) from mustard oil or wasabi, cinnamaldehyde, diallyl disulfide (DADS) from garlic, and acrolein, an irritant from tears gas and vehicule exhaust fumes. Acts also as an ionotropic cannabinoid receptor by being activated by delta(9)-tetrahydrocannabinol (THC), the psychoactive component of marijuana. Is activated by a large variety of structurally unrelated electrophilic and non-electrophilic chemical compounds. Electrophilic ligands activate TRPA1 by interacting with critical N-terminal Cys residues in a covalent manner, whereas mechanisms of non-electrophilic ligands are not well determined. May be a component for the mechanosensitive transduction channel of hair cells in inner ear, thereby participating in the perception of sounds. Probably operated by a phosphatidylinositol second messenger system.

Target Involvement

Episodic pain syndrome, familial, 1 (FEPS1)

Target Subcellular Location

Cell membrane; Multi-pass membrane protein.

Target Protein Families

Transient receptor (TC 1.A.4) family

Target Tissue Specificity

Expressed at very low level in human fibroblasts and at a moderate level in liposarcoma cells.

Target Synonyms

ANKTM 1; ANKTM1; Ankyrin-like with transmembrane domains protein 1; Transformation sensitive protein p120; Transformation-sensitive protein p120; Transient receptor potential cation channel subfamily A member 1; TRPA 1; Trpa1; TRPA1_HUMAN

Target Background

The structure of the protein encoded by this gene is highly related to both the protein ankyrin and transmembrane proteins. The specific function of this protein has not yet been determined; however, studies indicate the function may involve a role in signal transduction and growth control.
