Receptor for plasminogen. Regulates urokinase plasminogen activator-dependent and stimulates tissue-type plasminogen activator-dependent cell surface plasminogen activation. Proposed to be part of a local catecholaminergic cell plasminogen activation system that regulates neuroendocrine prohormone processing. Involved in regulation of inflammatory response; regulates monocyte chemotactic migration and matrix metalloproteinase activation, such as of MMP2 and MMP9. Interacts with PLAT and PLAUR. Colocalizes on the cell surface with urokinase plasminogen activator surface receptor/PLAUR. Expressed in peripheral blood cells and monocytes. Expressed in adrenal medulla.
