Acts upstream of or within negative regulation of neuron differentiation and positive regulation of Notch signaling pathway. Located in nucleolus. Is expressed in several structures, including adipose tissue; alimentary system; genitourinary system; integumental system; and nervous system. Human ortholog(s) of this gene implicated in anauxetic dysplasia 3. Orthologous to human NEPRO (nucleolus and neural progenitor protein). [provided by Alliance of Genome Resources, Apr 2022]
