Cayman 5-Oxo Leukotriene B4, 50ug

Optineurin (OPTN) is an adapter protein with roles in autophagy, vesicular trafficking, and inflammatory responses to viral and bacterial pathogens. OPTN binds to ubiquitinated cargo via its ubiquitin-binding domain and targets them for autophagic degradation by recruiting LC3-expressing phagophore membranes via its LC3-interacting region. It is phosphorylated by TANK binding kinase 1 (TBK1), which increases the binding affinity of OPTN for polyubiquitinated mitochondria, promotes TBK1 activation and recruitment to the mitochondria, and permits the degradation of damaged mitochondria via PINK1/parkin-dependent mitophagy. OPTN regulates transferrin receptor trafficking and recycling by mediating the association between the membrane trafficking protein Rab8 and its activator TBC1D17. Mutation of the OPTN ubiquitin binding domain reduces LPS- and poly(I:C)-induced increases in IFN-β levels in bone marrow-derived macrophages (BMDMs). OPTN knockout increases mortality and reduces plasma levels of TNF-α and IL-6 in a mouse model of E. coli-induced peritonitis. Mutations in OPTN are associated with primary open angle glaucoma, amyotrophic lateral sclerosis (ALS), Pagets disease, and Alzheimers disease.^, Caymans Optineurin Monoclonal Antibody (Clone 8E12) can be used for immunocytochemistry applications.
