Description
Neutrophil activating peptide 2 (NAP-2), connective tissue activating protein III (CTAP-III) and beta-thrombogulin (beta-TG), are proteolytically processed carboxy-terminal fragments of platelet basic protein (PBP), which is found in the alpha-granules of human platelets. NAP-2 is a member of the CXC chemokines and is named CXCL7. Similar to other ELR domain containing CXC chemokines, such as IL-8 and the GRO proteins, NAP-2 binds CXCR2 and chemoattracts and activates neutrophils
