Angio-associated, migratory cell protein, also known as AAMP, is a protein which in humans is encoded by the AAMP gene. This protein has been conserved in evolution and is so common to many mammals. It is found to be expressed strongly in the cytosol of endothelial cells, cytotrophoblasts, and poorly differentiated colon adenocarcinoma cells found in lymphatics and has been observed at the luminal edges of endometrial cells and in the extracellular environment of vascular-associated mesenchymal cells. AAMP helps to regulate vascular endothelial cell migration regulation and angiogenesis, with other signaling pathway like RhoA/Rho-kinase signaling. In all these diseases we can observe the expression of the AAMP gene. This one can either remain stable, increase or decrease depending on the disease. List of the diseases : gastrointestinal stromal tumor (GIST) (for this disease and the ductal carcinomas, the expression levels are to correlate with necrosis in situ), myeloid leukemia (chronic (CML) and acute (AML) forms), lymphoma, breast cancer, glial brain tumors, colon neoplasia, epidermoid carcinoma, cervical cancer, ovarian cancer, papillary thyroid cancer, pulmonary cancer, atherosclerosis, restenosis.

Flow cytometric analysis of HepG2 cells labeling AAMP.
Cells were fixed and permeabilized. Then stained with the primary antibody (HA721054, 1ug/ml) (red) compared with Rabbit IgG Isotype Control (green). After incubation of the primary antibody at +4℃ for an hour, the cells were stained with a Alexa Fluor® 488 conjugate-Goat anti-Rabbit IgG Secondary antibody at 1/1,000 dilution for 30 minutes at +4℃. Unlabelled sample was used as a control (cells without incubation with primary antibody; black).
