Biological activitySpecific activity is > 300 nmoles/min/mg, and is defined as the amount of enzyme that cleaves 1 µmole of suc-AAFP-pNA per minute at 25°C in Tris-Hcl pH 8.0 using chymotrypsin.
- Prepare 170 µl assay buffer into a suitable container and pre-chill on ice before use: The final concentrations are 200 mM Tris-Hcl, pH 8.0, and 20nM chymotrypsin.
- Add 10 µl of recombinant FKBP4 protein with 1 µg in assay buffer.
- Mix by inversion and equilibrate to 1°C and monitor the A405nm until the value is constant using a spectrophotometer.
- Add 20 µl pre-chilled 5mM suc-AAFP-pNA. (Substrate was dissolved in TFE that contained 460mM LiCl to a concentration of 3 mM)
- Record the increase in A405 nm for 30 minutes at 25°C.
Purity> 95 % SDS-PAGE.

- 52 kDa FK506-binding protein
FunctionImmunophilin protein with PPIase and co-chaperone activities (By similarity). Component of unliganded 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.
Tissue specificityWidely expressed.
Sequence similaritiesContains 2 PPIase FKBP-type domains.
Contains 3 TPR repeats.
DomainThe PPIase activity is mainly due to the fisrt PPIase FKBP-type domain (1-138 AA).
The C-terminal region (AA 375-458) is required to prevent tubulin polymerization.
The chaperone activity resides in the C-terminal region, mainly between amino acids 264 and 400.
modificationsPhosphorylation by CK2 results in loss of HSP90 binding activity (By similarity). Phosphorylated upon DNA damage, probably by ATM or ATR.
Cellular localizationCytoplasm > cytosol. Nucleus. Cytoplasm > cytoskeleton.
