Abstract excerpt
Leukemia inhibitory factor (LIF)-induced cell signaling occurs following sequential binding to the LIF receptor alpha-chain (LIFR), then to the gp130 co-receptor used by all members of the interleukin-6 family of cytokines. By monovalently displaying human LIF on the surface of M13 phage and randomizing clusters of residues in regions predicted to be important for human LIFR binding, we have identified mutations,...
