CXCL3/GRO gamma, also known as DCIP-1 in mouse and CINC-2 in rat, is a member of the CXC chemokine family. Human CXCL3/GRO gamma is 107 amino acids (aa) in length, which includes a proposed signal peptide (aa 1–34), with a predicted molecular weight of 11 kDa. The mouse and rat orthologs share 65% and 59% aa sequence identity with the human protein, respectively. Genome-wide analysis suggests that the protein encoded by the mouse Cxcl1 gene is homologous to human CXCL3/GRO gamma protein. CXCL3/GRO gamma is chemotactic for granulocytes, including neturophils.
