Several types of chemokine-binding proteins (CKBPs) have been identified (reviewed in [3]), including those that bind chemokines from multiple subfamilies, such as Myxoma-T7 (M-T7) from myxoma [4], M3 from γ-herpesvirus-68 [5,6,7,8], and the poxvirus-encoded smallpox virus-encoded chemokine receptor (SECRET) domain [9]. This evidence concerns the gene SCGN and myxoma.
