摘要:
Nucleic acid sequences encoding novel splice variants that encode subunits of an ENaC expressed in human taste tissue are provided. These splice variants when expressed in association with other ENaC subunits, i.e., α, β and γ subunits or α, β and Δ subunits may be used to produce amiloride-insensitive ENACs. The resultant amiloride-insensitive ENaCs are useful in in vitro assays for identifying ENaC modulators that modulate taste (enhance or inhibit), particularly human salty taste.
