General description

ICAM5 (intercellular adhesion molecule 5), also called telencephalin, is a neuronal cell adhesion molecule belonging to the ICAM family. This gene is localized to human chromosome 19p13.2 and spans 80kb. It is a glycoprotein, which is polarized towards the dendrites. This protein is composed of nine exoplasmic Ig (immunoglobulin) domain consisting of 832 amino acids. It is also composed of a transmembrane region of 28 amino acids, and a 64 amino acid-cytosolic region. It is exclusively expressed by neurons of telencephalon, which is the most rostral region of brain.


Intercellular adhesion molecule 5 precursor recombinant protein epitope signature tag (PrEST)


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

ICAM5 (intercellular adhesion molecule 5) shows hemophilic between neurons through binding between Ig (immunoglobulin) domain 1 to domain 4-5. It also interacts in a heterophilic manner with β2-integrins present on leukocytes. This proteinis involved in the arborization of hippocampal neurons and the outgrowth of dendrites. This protein interacts with LFA-1 (lymphocyte function-associated antigen-1) integrin present on microglia, which helps microglial spreading and regulates the function of microglia in both physiological and pathological conditions. Meta-analysis studies show that V301I and rs281439 polymorphisms in ICAM5 gene are responsible for susceptibility to breast cancer. This protein also functions as an anti-inflammatory agent in brain, where T-cell activation results in its cleavage from neurons.
