Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Storage Condition Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time 18-23 business days
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Proton-selective channel that specifically transports protons into cells. Proton channel activity is only weakly-sensitive to voltage. Proton-selective channel activity is probably required in cell types that use changes in intracellular pH for cell signaling or to regulate biochemical or developmental processes. In the vestibular system of the inner ear, required for the formation and function of otoconia, which are calcium carbonate crystals that sense gravity and acceleration. Probably acts by maintaining the pH appropriate for formation of otoconia. Regulates purinergic control of intracellular calcium in vestibular supporting cells. May be involved in sour taste perception in sour taste cells by mediating entry of protons within the cytosol. Also involved in energy metabolism, by reducing adipose tissue inflammation and protecting from obesity-induced metabolic dysfunction.
Gene References into Functions
  1. Otop1 defines a unique target of cytokine signaling that attenuates obesity-induced adipose tissue inflammation and plays an adaptive role in maintaining metabolic homeostasis in obesity. PMID: 24379350
  2. Data show that tlt and mlh mutations uncouple Otopetrin 1 from inhibition of P2Y receptor function. PMID: 21236346
  3. OTOP1 is expressed at the apex of supporting cells. It increases cytosolic Ca in response to purinergic agonists by blocking mobilization of Ca from intracellular stores in an extracellular Ca-dependent manner & by mediating extracellular Ca influx. PMID: 20554841
  4. a non-syndromic vestibular disorder with otoconial agenesis in tilted/mergulhador mice is caused by mutations in otopetrin 1 PMID: 12651873
  5. Otopetrin 1 encodes a multi-transmembrane domain protein expressed in the developing otocyst. Mouse mutants tilted and mergulhador carry recessive mutations in Otop1 that result in otoconial agenesis without causing collateral deafness. PMID: 12651873
