Functional Characteristics Click here for help
γ = 59–78 pS for monovalent ions at negative potentials, conducts mono- and di-valents with high selectivity for divalents (PCa/PNa > 107); voltage- and time- dependent inward rectification; inhibited by intracellular Ca2+ promoting fast inactivation and slow downregulation; feedback inhibition by Ca2+ reduced by calcium binding protein 80-K-H; inhibited by extracellular and intracellular acidosis; upregulated by 1,25-dihydrovitamin D3
Ion Selectivity and Conductance Comments
At present the only ion selectivity data available for TRPV5 is from rabbit studies. Ion selectivity is ordered Na+ > Li+ > K+ > Cs+ > NMDG+ (N-methyl-G-glucamine) [13], and Ca2+ > Ba2+ = Sr2+ > Mn2+ [24].

Overall single channel conductance is 72-82 pS [13]. Subject to Mg2+ block. PCa:PNa ratio > 100 [13,24].
Voltage Dependence Comments
Blocking by intracellular Mg2+ displays voltage dependency [13].
Activators (Human)
constitutively active (with strong buffering of intracellular Ca2+)
Other channel blockers (Human)
Pb2+ = Cu2+ = Gd3+ > Cd2+ > Zn2+ > La3+ > Co2+ > Fe2

Activator Comments
TRPV5 is constitutively active [24]. Its function is modulated by extracellular protons [25,27-28]. Parathyroid hormone, 17β-estradiol and 1,25-dihydroxyvitamin D(3) activate TRPV5 by upregulating its expression level as well as directly activating the channel [2,4,7,17]. Klotho increases plasma membrane TRPV5 abundance by hydrolysis of its extracellular N-linked oligosaccharides [1].
