Enables follicle-stimulating hormone receptor activity. Acts upstream of or within several processes, including G protein-coupled receptor signaling pathway; gonad development; and regulation of signal transduction. Located in cell surface. Is expressed in early conceptus and gonad. Human ortholog(s) of this gene implicated in 46 XX gonadal dysgenesis; ovarian dysgenesis 1; and ovarian hyperstimulation syndrome. Orthologous to human FSHR (follicle stimulating hormone receptor). [provided by Alliance of Genome Resources, Apr 2022]
