- AMICA is a 65kD, heavily glycosylated transmembrane protein that belongs to the junctional adhesion molecule (JAM) subset of the immunoglobulin superfamily. JAM family molecules contribute to intercellular connections within epithelial and endothelial cell layers, and mediate their interactions with various hemopoietic cells. The human AMICA cDNA encodes a 384 amino acid (aa) precursor that includes a 19 aa signal sequence, a 256aa extracellular domain (ECD) with two Ig-like domains, a 21aa transmembrane segment, and a 98aa cytoplasmic domain. Alternative splicing may generate isoforms with N- and C-terminal deletions. In contrast to other JAM family proteins, AMICA does not contain a cytoplasmic PDZ-binding motif. Within the ECD, human AMICA shares 58% and 63% aa sequence identity with mouse and rat AMICA, respectively. It shares 18%-20% aa sequence identity with the ECDs of human JAM-A, -B, -C and JAM4. AMICA is expressed on the surface of granulocytes and monocytes and is up-regulated during the differentiation of myeloid leukemia cells. A motif in the ECD, which promotes dimerization of other JAM family proteins, is required for surface localization of AMICA. AMICA mediates the adhesion of monocytes to endothelial cells and neutrophil migration across epithelial cell monolayers. This latter function involves specific interactions of AMICA with coxsackie virus and adenovirus receptor (CXADR) in epithelial tight junctions. In particular, the membrane proximal Ig-like domain of AMICA binds the membrane-distal Ig-like domain of CXADR. AMICA does not appear to interact homophilically, as neutrophils adhere to immobilized CXADR but not to immobilized AMICA. Applications: Suitable for use in Flow Cytometry. Other applications not tested. Recommended Dilution: Flow Cytometry: 10ul labels 1x10e5 cells or 50ul of packed whole blood. Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4°C in the dark. DO NOT FREEZE! Stable at 4°C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: PE conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap.
