5.B.1.1.6
Thyroid NADPH oxidase/peroxidase 1 (Dual oxidase 1; Duox1) with two EF band domains, responsive to Ca2+ regulation (De Deken et al., 2000; Edens et al., 2001).  Duox enzyme activities in epithelia are inhibited by compounds that block Hv1, but inhibition occurs through Hv1-independent mechanisms, supporting the idea that Hv1 is not required for Duox activity (Gattas et al. 2019).

Molecular Weight:177235.00
Species:Homo sapiens (Human) [9606]
Number of TMSs:6
