Enables steroid binding activity. Involved in regulation of postsynaptic membrane potential and regulation of synaptic vesicle exocytosis. Acts upstream of or within cellular sodium ion homeostasis and excretion. Located in GABA-ergic synapse. Is active in glutamatergic synapse. Is expressed in several structures, including central nervous system and genitourinary system. Used to study autosomal dominant pseudohypoaldosteronism type 1. Human ortholog(s) of this gene implicated in autosomal dominant pseudohypoaldosteronism type 1 and pseudohypoaldosteronism. Orthologous to human NR3C2 (nuclear receptor subfamily 3 group C member 2).
