General description

The gene immunoglobulin-like domain-containing receptor-1 (ILDR1) is mapped to human chromosome 3q13.33. ILDR1 is expressed in prostate, testis, pancreas, kidney, liver, and heart. The gene encodes three variants, two with membrane localization and one as cytoplasmic. The cytoplasmic variant is only detected in lymphoma samples.

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem/physiol Actions

Loss of function mutations in immunoglobulin-like domain-containing receptor-1 (ILDR1) leads to autosomal-recessive hearing impairment in humans. ILDR1 is present at the tricellular contacts of epithelial cells in mouse model. The protein is important for recruitment of tricellulin to tricellular contacts which helps in the establishment of a strong barrier of epithelium. However, ILDR1 is not significant for tricellulin recruitment in the auditory and vestibular sensory epithelia or in the stria vascularis, but is required for tricellilin retention and integrity of tricellular tight junctions which is essential for normal hearing. ILDR1 is expressed in cholecystokinin cells. It regulates the release of cholecystokinin gastrointestinal hormone in the presence of lipoproteins and intestinally absorbed fatty acids. ILDR1 is up-regulated in myelodysplastic syndrome, refractory anemia with excess blasts.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.
