Product details:
Human FKBP12 ELISA Kit (ab277418) is an
in-vitro
enzyme-linked immunosorbent assay for the quantitative measurement of Human FKBP12 in serum (human FKBP12 concentration is low in normal serum/plasma, and may not be detectable in this assay), plasma and cell culture supernatants.
This assay employs an antibody specific for Human FKBP12 coated on a 96-well plate. Standards and samples are pipetted into the wells and Human FKBP12 present in a sample is bound to the wells by the immobilized antibody. The wells are washed, and biotinylated anti-Human FKBP12 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Human FKBP12 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

FKBP12 also known as FKBP-12 or FKBP12 protein is a small protein with a molecular weight of approximately 12 kDa. It belongs to the family of immunophilins and acts as a peptidyl-prolyl cis-trans isomerase (PPIase) facilitating the folding of proteins by catalyzing the isomerization of proline residues in polypeptides. The FKBP12 protein is expressed in various tissues throughout the body including the brain heart and skeletal muscles. It plays a mechanical role in binding certain macrolide antibiotics such as FK506 (tacrolimus) influencing their biological effects by altering protein conformation.
Biological function summary
FKBP12 is significant in cellular mechanisms beyond protein folding. It interacts with and forms complexes with other proteins such as ryanodine receptors and transforming growth factor-beta (TGF-β) receptors impacting calcium signaling and cell growth. FKBP12's interaction with FK506 has been extensively studied because it forms a complex that inhibits calcineurin ultimately leading to immunosuppressive effects. This property of FKBP12 makes it important for modulating the immune response and has importance in transplant medicine.
Pathways
FKBP12 is actively involved in calcium signaling and TGF-β signaling pathways. FKBP12 influences these pathways by binding to ryanodine receptors affecting calcium release from intracellular stores and also modulating the function of TGF-β receptors impacting cellular growth and proliferation processes. It is associated with proteins such as calcineurin and Smad proteins in these pathways maintaining cellular homeostasis and regulating immune and inflammatory responses.
FKBP12 plays a role in immunological and proliferative diseases. It is implicated in autoimmune disorders due to its interaction with FK506 leading to the suppression of unwanted immune responses. FKBP12 is also linked to cardiac hypertrophy as its modulation of calcium release through ryanodine receptors can affect heart muscle function. The protein interacts with calcineurin in these contexts contributing to pathological processes in these diseases. Researchers target FKBP12 with ELISA and other assays to investigate its involvement in these disorders and assess therapeutic interventions.
