Enables anti-Mullerian hormone receptor activity. Acts upstream of or within anti-Mullerian hormone signaling pathway; negative regulation of anti-Mullerian hormone signaling pathway; and sex differentiation. Predicted to be integral component of plasma membrane. Predicted to be part of activin receptor complex. Predicted to be active in plasma membrane. Is expressed in several structures, including early embryo; forebrain; genitourinary system; and nose. Used to study persistent Mullerian duct syndrome. Human ortholog(s) of this gene implicated in persistent Mullerian duct syndrome. Orthologous to human AMHR2 (anti-Mullerian hormone receptor type 2).
