Paclitaxel (Taxol), an effective anticancer agent, is known to bind to tubulin and induce tubulin polymerization. Several other binding proteins of paclitaxel, such as Bcl-2, heat shock proteins, and NSC-1, have also been reported. Here, we describe a T7 phage-based display to screen for paclitaxel-binding molecules from a random peptide library using paclitaxel-photoimmobilized TentaGel resin. Specific phage particles that bind the paclitaxel-immobilized resin were obtained. Among them, two phage clones included the same consensus amino acid sequence (KACGRTRVTS). Analysis of the protein database using BLAST revealed that a portion of this sequence is conserved in the zinc finger domain of human NFX1. Binding affinity of paclitaxel against the partial recombinant protein of NFX1 (424aa-876aa) was confirmed by pull-down assays and surface plasmon resonance analyses.
