N-ETHYL-N-(3-CARBOXYPROPYL)NITROSAMINE

N-Alkyl-N-(3-carboxypropyl)nitrosamines are known to selectively induce urinary bladder tumor in rats and mice.

Opsins are members of the guanine nucleotide-binding protein (G protein)-coupled receptor superfamily. In addition to the visual opsins, mammals possess several photoreceptive non-visual opsins th at are expressed in extraocular tissues. This gene, opsin 3, is strongly expressed in brain and testis and weakly expressed in liver, placenta, heart, lung, skeletal muscle, kidney, and pancreas. The gene may also be expressed in the retina. The protein has the canonical features of a photoreceptive opsin protein. [provided by RefSeq]

Questionable carcinogen withexperimental tumorigenic data. Mutation data reported.Many N-nitroso compounds are carcinogens. Whenheated to decomposition it emits toxic fumes of NOx. Seealso N-NITROSO COMPOUNDS and AMINES.
