Enables several functions, including DNA-binding transcription activator activity, RNA polymerase II-specific; gamma-tubulin binding activity; and promoter-specific chromatin binding activity. Acts upstream of or within several processes, including nervous system development; neurotrophin TRK receptor signaling pathway; and regulation of transcription, DNA-templated. Located in several cellular components, including centrosome; cytosol; and nucleus. Part of protein-containing complex. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; limb; and sensory organ. Used to study Prader-Willi syndrome. Human ortholog(s) of this gene implicated in Prader-Willi syndrome. Orthologous to human NDN (necdin, MAGE family member). [provided by Alliance of Genome Resources, Apr 2022]
