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. Interacts with PLAUR (By similarity). Colocalizes on the cell surface with urokinase plasminogen activator surface receptor/Plaur. Expressed in monocytes; detected in differentiated monocytes but not in progenitor cells. Expressed in adrenal medulla and hippocampus.
