Summary: Predicted to enable several functions, including beta-carotene 15,15'-dioxygenase activity; carboxylic ester hydrolase activity; and phospholipid binding activity. Predicted to be involved in several processes, including detection of light stimulus involved in visual perception; retina homeostasis; and terpenoid metabolic process. Located in cytoplasm; nucleus; and plasma membrane. Is expressed in eye and urinary system. Used to study Leber congenital amaurosis 2 and retinitis pigmentosa 20.

Rod a-wave and cone b-wave amplitudes of electroretinograms were increased in Cntf (-/-) mice, but rod b-wave amplitudes were unchanged compared with those in WT mice.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
