Anti-paired immunoglobin-like type 2 receptor alpha

The Uses of Anti-paired immunoglobin-like type 2 receptor alpha

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.

The Uses of Anti-paired immunoglobin-like type 2 receptor alpha

Anti-PILRA antibody produced in rabbit is suitable for western blotting at a concentration of 5μg/mL. It is also useful for immunohistochemistry at a concentration of 4-8μg/mL.

General Description

Cell signaling pathways rely on a dynamic interaction between activating and inhibiting processes. SHP-1-mediated dephosphorylation of protein tyrosine residues is central to the regulation of several cell signaling pathways. Two types of inhibitory receptor superfamily members are immunoreceptor tyrosine-based inhibitory motif (ITIM)-bearing receptors and their non-ITIM-bearing, activating counterparts. Control of cell signaling via SHP-1 is thought to occur through a balance between PILRalpha-mediated inhibition and PILRbeta-mediated activation. These paired immunoglobulin-like receptor genes are located in a tandem head-to-tail orientation on chromosome 7. This particular gene encodes the ITIM-bearing member of the receptor pair, which functions in the inhibitory role. Alternative splicing has been observed at this locus and three variants, each encoding a distinct isoform, are described. (provided by RefSeq)

Biochem/physiol Actions

PILRA (Paired immunoglobin-like type 2 receptor alpha) gene encodes a single-pass type I membrane protein predominantily expressed in immune cells like monocytes, granulocytes and dendritic cells. PILR-associating neural protein (PANP) is a ligand for PILRA that facilitates the immune system regulation. It plays a pivotal role in regulating cell signaling via SHP-1 by balancing the PILRalpha-mediated inhibition and PILRbeta-mediated activation. Additionally, PILRalpha facilitates as a coreceptor that acquaints with glycoprotein B (gB) and assists in herpes simplex virus-1 entry. Further, it regulates the membrane fusion of the viral envelope with cellular membranes during virus entry and virus-induced cell-to-cell fusion.
