Chain A,B   (TIMD2_MOUSE | Q8R183)
molecular function
    GO:0070287    ferritin receptor activity    Combining with ferritin, and delivering ferritin into the cell via endocytosis.
biological process
    GO:0097286    iron ion import    The directed movement of iron ions into a cell or organelle.
    GO:0006898    receptor-mediated endocytosis    An endocytosis process in which cell surface receptors ensure specificity of transport. A specific receptor on the cell surface binds tightly to the extracellular macromolecule (the ligand) that it recognizes; the plasma-membrane region containing the receptor-ligand complex then undergoes endocytosis, forming a transport vesicle containing the receptor-ligand complex and excluding most other plasma-membrane proteins. Receptor-mediated endocytosis generally occurs via clathrin-coated pits and vesicles.
cellular component
    GO:0009986    cell surface    The external part of the cell wall and/or plasma membrane.
    GO:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
