  • PSMA-specific binding proteins
    Patent number: 11464877
    Abstract: The present invention relates to a prostate-specific membrane antigen (PSMA)-specific binding protein, wherein the PSMA-specific binding protein is a lipocalin 2 (Lcn2)-derived binding protein and binds to PSMA with a KD of 10 nM or lower. The present invention also relates to a nucleic acid molecule encoding the PSMA-specific binding protein of the invention, a vector comprising said nucleic acid molecule of the invention and a host cell transformed with the vector. Furthermore, the invention relates to a method of producing the PSMA-specific binding protein of the invention, the method comprising culturing the host cell of the invention under suitable conditions and isolating the PSMA-specific binding protein produced. The present invention further relates to a protein conjugate comprising the PSMA-specific binding protein of the invention, or the PSMA-specific binding protein produced by the method of the invention.
