P67phox is central to the activation of NADPH oxidase, which is critical for superoxide production. p67phox forms heterodimers with CYBA and CYBB and interacts with NCF4 and NCF1 to establish important connections within the complex. p67phox Protein, Human (sf9) is the recombinant human-derived p67phox protein, expressed by Sf9 insect cells, with tag free and with additional two amino acids (Gly & Pro) at the N-terminus.
