Summary: Nitric oxide is a reactive free radical which acts as a biologic mediator in several processes, including neurotransmission and antimicrobial and antitumoral activities. This gene encodes a nitric oxide synthase that is inducible by a combination of lipopolysaccharide and certain cytokines. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Sep 2015]

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.

mRNA and Protein(s)

NM_001313921.1 → NP_001300850.1 nitric oxide synthase, inducible isoform b

Status: REVIEWED

Description

Transcript Variant: This variant (2) contains an alternate exon in place of the first two exons compared to variant 1. This difference results in translation initiation at a downstream start codon and an isoform (b) that is shorter at the N-terminus compared to isoform a. Variants 2 and 3 both encode the same isoform (b).
