P PF08944 p47_phox_C NADPH oxidase subunit p47Phox, C terminal domain Domain The C terminal domain of the phagocyte NADPH oxidase subunit p47Phox contains conserved PxxP motifs that allow binding to SH3 domains, with subsequent activation of the NADPH oxidase, and generation of superoxide, which plays a crucial role in host defense against microbial infection [1]. PFAM PF08944
S PF00018 SH3_1 SH3 domain Domain SH3 (Src homology 3) domains are often indicative of a protein involved in signal transduction related to cytoskeletal organisation. First described in the Src cytoplasmic tyrosine kinase Swiss:P12931. The structure is a partly opened beta barrel. PFAM PF00018
