Structural Analysis and Docking Studies of FK506-Binding Protein 1A

Abstract

FK-binding protein 1A, a member of immunophilin family of proteins, is a protein with a wide variety of roles in cellular processes, including regulation of immune system, calcium intake metabolism through ryanodine receptors, TGF-{beta} signaling and EGFR regulation. As a protein originally defined as the cellular target of premier immunosuppresant drugs, FK506 and Rapamycin, it has been a protein studied for further pharmacological uses. In this study, we have overexpressed, purified and crystallized apo-FKBP1A. Here, we are showing the FKBP1A crystal structure, calculated at cryogenic temperature at a very high resolution of 1.05 [A], obtained with a home source X-ray Turkish DeLight. Docking studies, with drug repurposing in mind were carried out with Molegro Virtual Docker software. Docking results will prove useful in future pharmaceutical studies done on FKBP1A, and similar proteins.
