Localization of brain nitric oxide synthase (NOS) to human chromosome 12.
Recent research has shown that nitric oxide is a novel neuronal second messenger and transmitter that may be involved in neuronal cell death and damage in neurological illness. To map the chromosomal localization of this important brain enzyme, a rat cDNA probe was prepared by RNA PCR from rat cerebellum RNA. This rat cDNA was used to isolate a human nitric oxide synthase (NOS) cDNA from a human cerebellum cDNA library. The human cDNA clone containing 1.2 kb of brain NOS cDNA was hybridized to Southern blots containing DNAs obtained from human-rodent hybrid cell line panels using EcoRI and HindIII digestion to ascertain the location of the human NOS gene. These data showed that the human brain nitric oxide synthase mapped within 12q14-qter on human chromosome 12.
