Immunohistochemistry was performed on normal biopsies of deparaffinized human tonsil tissue. To expose target proteins, heat induced antigen retrieval was performed using 10mM sodium citrate (pH 6.0) buffer, microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1/50 with a rabbit polyclonal antibody recognizing FKBP12 (ab2918) or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP, followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.

Supplementary information

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.

Target data

Keeps in an inactive conformation TGFBR1, the TGF-beta type I serine/threonine kinase receptor, preventing TGF-beta receptor activation in absence of ligand. Recruits SMAD7 to ACVR1B which prevents the association of SMAD2 and SMAD3 with the activin receptor complex, thereby blocking the activin signal. May modulate the RYR1 calcium channel activity. PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides.
