A synthetic peptide from aa region 250-300 of mouse CAHM1 conjugated to blue carrier protein was used as the antigen. The antigen shares 97% identity with the rat sequence.
Calcium homeostasis modulator protein 1
Function: 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.
Subcellular location: Cell membrane; Multi-pass membrane protein; Endoplasmic reticulum membrane; Multi-pass membrane protein
Tissue specificity: Specifically expressed in type II taste bud cells. Not expressed in brain.
Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.
