Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B   (CRC1_HOMGA | P80029)
molecular function
    GO:0031409    pigment binding    Interacting selectively and non-covalently with a pigment, any general or particular coloring matter in living organisms, e.g. melanin.
    GO:0036094    small molecule binding    Interacting selectively and non-covalently with a small molecule, any low molecular weight, monomeric, non-encoded molecule.
biological process
    GO:0006810    transport    The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
    GO:0005615    extracellular space    That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
