Predicted to enable metal ion binding activity. Involved in circadian regulation of gene expression. Acts upstream of or within regulation of growth; regulation of transcription by RNA polymerase II; and skeletal system development. Located in nucleus. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; limb bud; and sensory organ. Used to study Potocki-Lupski syndrome and Smith-Magenis syndrome. Human ortholog(s) of this gene implicated in Smith-Magenis syndrome. Orthologous to human RAI1 (retinoic acid induced 1).
