Anti-DAP1/DAP Antibody Picoband®

Death-associated protein 1 is a protein that in humans is encoded by the DAP gene. This gene encodes a basic, proline-rich, 15-kD protein. The protein acts as a positive mediator of programmed cell death that is induced by interferon-gamma. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.

A synthetic peptide corresponding to a sequence at the C-terminus of human DAP1/DAP, which shares 92.9% amino acid (aa) sequence identity with both mouse and rat DAP1/DAP.

LA-PF4 stimulates DNA synthesis, mitosis, glycolysis, intracellular cAMP accumulation, prostaglandin E2 secretion, and synthesis of hyaluronic acid and sulfated glycosaminoglycan. It also stimulates the formation and secretion of plasminogen activator by human synovial cells. NAP-2 is a ligand for CXCR1 and CXCR2, and NAP-2, NAP-2 (73), NAP-2 (74), NAP-2 (1-66), and most potent NAP-2 (1-63) are chemoattractants and activators for neutrophils. TC-1 and TC-2 are antibacterial proteins, in vitro released from activated platelet alpha-granules. CTAP-III (1-81) is more potent than CTAP-III desensitize chemokine-induced neutrophil activation.
