Species Human
Protein Type Recombinant
Applications SDS-PAGE
Assay Information 1. Prepare assay buffer in a suitable container and pre-chill on ice before use: The final concentrations are 35 mM Tris, pH 8.0, 1uM suc-AAFP-pNA). 2. Add recombinant FKBP1a protein with various concentrations (1ug, 2ug, 5ug) in assay buffer. 3. Mix by inversion and equilibrate to 1 DEG C and monitor the A410nm until the value is constant using a spectrophotometer. 4. Add pre-chilled chymotrypsin to 12.5 uM and mix immediately. 5. Record the increase in A410 nm for 20 minutes

General Information

Biological Significance FK506 binding protein 1a, also known as FKBP12, belongs to the immunophilin protein family, which play a role in immunoregulation and basic cellular processes involving protein folding and trafficking. FKBP12 also plays a role in intracellular calcium regulation by associating with three types of calcium release channel complexes, cardiac and skeletal ryanodine receptors and the inositol 1,4,5-trisphosphate receptor. It interacts with several intracellular signal transduction proteins including type I TGF-beta receptor. Recombinant human FKBP12, fused to His-tag at N-terminus, was expressed in E. coli and purified by using conventional chromatography.
