[https://www.uniprot.org/uniprot/FKBP4_HUMAN FKBP4_HUMAN] Immunophilin protein with PPIase and co-chaperone activities (By similarity). Component of unligated steroid receptors heterocomplexes through interaction with heat-shock protein 90 (HSP90). May play a role in the intracellular trafficking of heterooligomeric forms of steroid hormone receptors between cytoplasm and nuclear compartments (By similarity). The isomerase activity controls neuronal growth cones via regulation of TRPC1 channel opening. Acts also as a regulator of microtubule dynamics by inhibiting MAPT/TAU ability to promote microtubule assembly. May have a protective role against oxidative stress in mitochondria.<ref>PMID:1279700</ref> <ref>PMID:1376003</ref> <ref>PMID:2378870</ref> <ref>PMID:19945390</ref> <ref>PMID:21730050</ref>

FKBP52 is a member of the FK506-binding protein family (FKBPs). The N-terminal domain of FKBP52 (FKBP52-N; residues 1-140) is responsible for peptidyl-prolyl isomerase activity and binding of FK506. Here, the crystal structure of FKBP52-N has been determined by molecular replacement to 2.4 A. FKBP52-N is defined by a six-stranded antiparallel beta-sheet wrapping with a right-handed twist around a short alpha-helix, an architecture similar to that of FKBP12. FKBP52-N is able to bind FK506 in a similar way to FKBP12. The variability in two loop regions (residues 70-76 and 108-127) is the principal reason for the specificity differences between FKBP52-N and FKBP12. The Pro120 change corresponding to Gly89 in FKBP12 limits the conformational adaptation between the loop (residues 108-127) and FK506 and decreases the FK506 affinity, while the Lys121 substitution corresponding to Ile90 of FKBP12 destroys a key interaction between FKBP52-N and calcineurin. It can be inferred from the locations of strictly conserved amino acids in the polypeptide chain that the maintenance of the overall conformation of the PPIase domains of FKBPs is essential for the PPIase activity. The N-terminal region and beta-sheets of FKBP52-N forms a hydrophobic patch which may be responsible for the binding of target proteins such as dynein or PAHX.
