Acts upstream of or within several processes, including angiogenesis; negative regulation of Notch signaling pathway involved in somitogenesis; and somite rostral/caudal axis specification. Is expressed in several structures, including cardiovascular system; central nervous system; genitourinary system; paraxial mesenchyme; and retina. Orthologous to human NRARP (NOTCH regulated ankyrin repeat protein). [provided by Alliance of Genome Resources, Apr 2022]
