  • PubMed Abstract: 

    FKBP42 is a membrane-anchored immunophilin playing a critical role in morphogenesis and development of higher plants. We present the X-ray structure of the cytoplasmic portion of FKBP42 comprising both the FKBP-like domain and the TPR domain at 2.85 A resolution. The data shed light on the probable binding modes of key interaction partners, including HSP90 and two classes of ABC transporters. The resulting models provide a structural background for further investigation of the unique biological properties of this protein.
