TY - T1 - Phosphorylation of the α-chain in the integrin LFA-1 enables β2-chain phosphorylation and α-actinin binding required for cell adhesion SN - / UR - http://hdl.handle.net/10138/303101 T3 - A1 - Jahan, Farhana; Madhavan, Sudarrshan; Rolova, Taisia; Viazmina, Larisa; Grönholm, Mikaela; Gahmberg, Carl G. A2 - PB - Y1 - 2018 LA - eng AB - The integrin leukocyte function-associated antigen-1 (LFA-1) plays a pivotal role in leukocyte adhesion and migration, but the mechanism(s) by which this integrin is regulated has remained incompletely understood. LFA-1 integrin activity requires phosphorylation of its 2-chain and interactions of its cytoplasmic tail with various cellular proteins. The -chain is constitutively phosphorylated and necessary for cellular adhesion, but how the -chain regulates adhesion has remained enigmatic. We now...
