NMR Structure(hide GO term definitions)
Chain A   (GBP_MYTSE | Q27913)
molecular function
    GO:0005125    cytokine activity    Functions to control the survival, growth, differentiation and effector function of tissues and cells.
    GO:0008083    growth factor activity    The function that stimulates a cell to grow or proliferate. Most growth factors have other actions besides the induction of cell growth or proliferation.
biological process
    GO:0035099    hemocyte migration    The directed movement of a hemocyte within the embryo. Hemocytes are blood cells associated with a hemocoel (the cavity containing most of the major organs of the arthropod body) which are involved in defense and clotting of hemolymph, but not involved in transport of oxygen. In Drosophila, embryonic hemocytes originate from the head mesoderm as a cluster of cells. The cluster splits into two and one group of cells crosses the amnioserosa. Both populations then spread toward the middle of the embryo and then disperse evenly throughout the embryo.
    GO:0051781    positive regulation of cell division    Any process that activates or increases the frequency, rate or extent of cell division.
    GO:0032225    regulation of synaptic transmission, dopaminergic    Any process that modulates the frequency, rate or extent of dopaminergic synaptic transmission, the process of communication from a neuron to another neuron across a synapse using the neurotransmitter dopamine.
cellular component
    GO:0005575    cellular_component    The part of a cell, extracellular environment or virus in which a gene product is located. A gene product may be located in one or more parts of a cell and its location may be as specific as a particular macromolecular complex, that is, a stable, persistent association of macromolecules that function together.
    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.
