Also known as: IAP; dIAP; Akp-3
Summary: Predicted to enable alkaline phosphatase activity; metal ion binding activity; and protease binding activity. Acts upstream of or within neural tube development; neurogenesis; and post-anal tail morphogenesis. Located in brush border. Is expressed in duodenum; intestine; and jejunum. Human ortholog(s) of this gene implicated in inflammatory bowel disease. Orthologous to human ALPG (alkaline phosphatase, germ cell) and ALPI (alkaline phosphatase, intestinal).

Title: A role for intestinal alkaline phosphatase in preventing liver fibrosis.
data do not support a functional role of AKP3 in adipose tissue development, or insulin sensitivity
Title: Adiposity and metabolic health in mice deficient in intestinal alkaline phosphatase.
intestinal Akp3 deletion affects Na+-dependent Pi transport in the small intestine. In the adenine-induced renal failure model, Akp3 is predicted to be a factor contributing to suppression of the plasma Pi concentration.
Title: A Role of Intestinal Alkaline Phosphatase 3 (Akp3) in Inorganic Phosphate Homeostasis.
Authors found that Akp3(-/-) mice acquired lipopolysaccharide tolerance during postweaning development, suggesting that Akp3 plays an important role in immune education.
Title: Intestinal alkaline phosphatase deficiency leads to lipopolysaccharide desensitization and faster weight gain.
Intestinal alkaline phosphatase prevents metabolic syndrome in mice.
Title: Intestinal alkaline phosphatase prevents metabolic syndrome in mice.
These data suggest that IAP is a local immunomodulating factor, perhaps regulating LPS-toll-like receptor 4 (TLR4) interaction between commensal microflora and intestinal epithelium.
Title: A role for intestinal alkaline phosphatase in the maintenance of local gut immunity.
Intestinal alkaline phosphatase activity may have a role in mediating the accelerated fatty acid intake observed in Akp3 knockout mice fed a high-fat diet.
Title: A novel phosphatase upregulated in Akp3 knockout mice.
Results suggest that intestinal alkaline phosphatase participates in a rate-limiting step regulating fat absorption.
Title: Accelerated fat absorption in intestinal alkaline phosphatase knockout mice.
forced high-fat chow induced an 18% greater body weight gain, hepatic steatosis, and visceral fat accumulation in female Akp3(-/-) mice but not in female wild-type controls. there is 2X increase of lipid absorption in Akp3(-/-) male mice.
Title: Disruption of the murine intestinal alkaline phosphatase gene Akp3 impairs lipid transcytosis and induces visceral fat accumulation and hepatic steatosis.

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.
