chemokine mediated signaling pathway CXC chemokine mediated signaling pathway 2010-11-04T11:30:26Z PW:0000830 The CXC family members are characterized by the presence of two cysteine resides separated by one amino acid. CXC and CC are the two most prominent families. This family of chemokines is also subdivided into two subgroups: the one with the ELR motif - ELR (+) and the one without - ELR(-), respectively. Generally, ELR(+) and ELR(-) members bind to distinct chemokine, G-coupled protein, receptors. The effects of their signaling is for the most part angiogenic or angiostatic, respectively. pathway vpetri
