MRC2 Protein, Human (HEK293, His)

The MRC2 protein is implicated in potentially playing a role as an endocytotic lectin receptor with calcium-dependent lectin activity. It functions by internalizing glycosylated ligands from the extracellular space, releasing them in an endosomal compartment through clathrin-mediated endocytosis. MRC2 may be involved in the plasminogen activation system, controlling the extracellular levels of PLAUR/PLAU and thus regulating protease activity at the cell surface. Additionally, it is suggested to contribute to the cellular uptake, remodeling, and degradation of extracellular collagen matrices, potentially influencing collagen turnover during cancer progression and other chronic tissue destructive diseases. MRC2's involvement in the remodeling of the extracellular matrix is proposed to collaborate with matrix metalloproteinases (MMPs). It interacts with the C-terminal region of type I collagen/COL1A1, forms a tri-molecular complex with PLAUR/UPAR and PLAU/pro-UPA, and directly interacts with collagen V, highlighting its versatile role in cellular processes related to extracellular matrix dynamics.
