Gene type: protein coding
RefSeq status: PROVISIONAL
Organism: Rattus norvegicus
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Rattus
Also known as: Nat2a
Summary: Enables arylamine N-acetyltransferase activity. Involved in several processes, including digestive tract development; response to hypoxia; and response to lipopolysaccharide. Predicted to be located in cytoplasm. Biomarker of end stage renal disease. Human ortholog(s) of this gene implicated in several diseases, including autoimmune disease (multiple); carcinoma (multiple); contact dermatitis (multiple); leukemia (multiple); and lung disease (multiple). Orthologous to several human genes including NAT1 (N-acetyltransferase 1). [provided by Alliance of Genome Resources, Dec 2024]
Annotation information: Note: Loci in other organisms that are functionally homologous to this one are validly referred to as both NAT1 and NAT2; i.e., the functional homologs of NAT1 include mouse and rat Nat2, while the functional homologs of human NAT2 include mouse and rat Nat1. Name:sequence associations are consistent with current use in the field. [13 Feb 2013]
Expression: Biased expression in Thymus (RPKM 36.2), Spleen (RPKM 31.0) and 9 other tissues See more

High NAT2 expression is associated with mammary tumor susceptibility.
Title: Congenic rats with higher arylamine N-acetyltransferase 2 activity exhibit greater carcinogen-induced mammary tumor susceptibility independent of carcinogen metabolism.
High-altitude hypoxia decreases the activity and expression of CYP1A1 and NAT2, but increases that of CYP2D6.
Title: Effect of exposure to acute and chronic high-altitude hypoxia on the activity and expression of CYP1A2, CYP2D6, CYP2C9, CYP2C19 and NAT2 in rats.
Results demonstrate differential tissue-specific and developmental regulation of the rat Nat1 and Nat2 genes.
Title: Quantitative tissue and gene-specific differences and developmental changes in Nat1, Nat2, and Nat3 mRNA expression in the rat.
In homozygous rapid, homozygous slow, and heterozygous intermediate Nat2 congenic rat lines, Nat2 activities were observed in all tested tissues and found to be Nat2-genotype-dependent.
Title: Systemic functional expression of N-acetyltransferase polymorphism in the F344 Nat2 congenic rat.
RT-PCR experiments demonstrated that the relative expression of the rNat transcripts in liver and 12 extrahepatic tissues was rNat1 > rNat2, while rNat3 transcripts were not detected.

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.
