Description

Antigen: human and rat amino acids 130-149 (QHRRKELETRQKQYRWMEWN); The sequence is 95% homologous to 5-LO from mouse and hamster · Host: rabbit · Application(s): WB · 5-Lipoxygenase (5-LO) catalyzes the formation of 5(S)-HpETE from arachidonic acid as well as its subsequent conversion to leukotriene A4.1 5-LO is located in the cytosol of quiescent cells. Upon stimulation of the cell, 5-LO translocates to the nuclear membrane where it is found in association with 5-LO activating protein (FLAP) and with the 85 kDa cPLA2.2,3 5-LO has a molecular mass of approximately 78 kDa. The enzyme is predominately expressed in peripheral blood leukocytes and also in eosinophils, mast cells, epithelial cells, and alveolar macrophages isolated from lung.4
