Abstract：
:Interleukin (IL)-6 is an important cytokine in inflammatory processes, differentiation and growth. The IL-6 receptor complex comprises the specific IL-6 receptor (gp80) and two molecules of the signal tranducing component gp130 which transduces the signal into the nucleus via the Jak-STAT pathway. Both, gp80 and gp130 are sorted preferentially to the basolateral membrane of polarised Madin-Darby canine kidney (MDCK) cells. Previously, we have shown that gp130 partially localises to detergent-resistant membranes (DRMs)/lipid rafts and that lipid raft integrity is crucial for signalling to occur. Here we now demonstrate that wild-type gp80 is associated with DRMs only to a minor extent. However, gp80 mutants which lack parts of the cytoplasmic domain and therefore are more apically expressed than the wild type show an increased affinity for the liquid-ordered membrane domain. Studies with non-polarised MDCK cells suggest that the lipid raft association of the different mutants of gp80 precedes the establishment of cell polarity. Our findings suggest that lipid rafts play a role in the sorting of apically targeted gp80.
