Function

[CSF3_BOVIN] Granulocyte/macrophage colony-stimulating factors are cytokines that act in hematopoiesis by controlling the production, differentiation, and function of 2 related white cell populations of the blood, the granulocytes and the monocytes-macrophages. This CSF induces granulocytes.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

Publication Abstract from PubMed

The crystal structures of recombinant canine and bovine granulocyte colony stimulating factor (G-CSF) have been determined by X-ray crystallography, using molecular replacement with recombinant human G-CSF as a model. G-CSF is a member of the cytokine family of glycoproteins that stimulate the differentiation and proliferation of blood cells. Human, bovine and canine G-CSF all have a molecular mass of about 19 kDa and share an amino acid sequence identity of about 80%. Two crystal forms of canine G-CSF have been solved. Form I recombinant canine G-CSF (rcG-CSFI; space group C2) contains one molecule in the asymmetric unit while form II canine G-CSF (rcG-CSFII; space group P2(1)) has two molecules in the asymmetric unit and bovine G-CSF (rbG-CSF; space group P2(1)2(1)2(1)) contains one molecule in the asymmetric unit. rcG-CSFI has been refined to an R factor of 20.7% with data to 2.3 A resolution and rcG-CSFII has been refined to an R factor of 19.3% with data to 2.2 A resolution. rbG-CSF has been refined to an R factor of 21.3% with data to 1.7 A resolution. The structure of human, canine and bovine G-CSF is an antiparallel 4-alpha-helical bundle with up-up-down-down connectivity. With the exception of one highly exposed loop (residues 66 to 74), the human, canine and bovine structures are very similar to each other. Using our series of G-CSF crystal structures we developed a function that describes the probability that a particular residue position (i) contributes to a G-CSF receptor binding site based on two principles, (1) high sequence conservation in the primary sequence of human, bovine, canine and murine G-CSF and (2) conservation of high solvent accessibility in the human, bovine and canine crystal structures. On the basis of this probability function as well as a comparison of G-CSF to the crystal structure of human growth hormone (hGH) complexed with the extracellular domain of the human growth hormone receptor (hGHbp), residues that contribute to potential G-CSF receptor binding sites are identified.
