Predicted to enable several functions, including endopeptidase activator activity; proteasome binding activity; and ubiquitin binding activity. Involved in several processes, including germ cell development; gonad development; and positive regulation of growth hormone receptor signaling pathway. Predicted to be located in cytosol; nucleoplasm; and plasma membrane. Predicted to be part of proteasome regulatory particle, lid subcomplex. Is expressed in genitourinary system; sensory organ; and skeleton. Orthologous to human ADRM1 (ADRM1 26S proteasome ubiquitin receptor). [provided by Alliance of Genome Resources, Apr 2022]
