Primary antibody notes
Immunophilins are a family of soluble receptors capable of binding to one of two major immunosuppressant agents; cyclosporin A (CsA) or FK506. Proteins that bind FK506 are termed FK506 Binding Proteins (FKBPs) and those that bind cyclosporin A are called cyclophilins (CyP). Immunophilins function as cis-trans peptidyl-prolyl isomerases (PPIase) whose activity is inhibited by their respective immunosuppressant compounds. Thus, immunophilins accelerate folding of some proteins both in vivo and in vitro by catalyzing slow steps in the initial folding and rearrangement of proline-containing proteins. FKBP12:FK506 complexes inhibit calcineurin, a calcium/calmodulin-dependent serine/threonine phosphatase which blocks T-cell activation by preventing lymphokine gene transcription. 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. In interactions with members of the TGF beta family type I receptors, FKBP12 has been shown to exert an inhibitory effect on the signaling pathway. -

Target

Function
May play a role in modulation of ryanodine receptor isoform-1 (RYR-1), a component of the calcium release channel of skeletal muscle sarcoplasmic reticulum. There are four molecules of FKBP12 per skeletal muscle RYR. PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. -
Sequence similarities
Belongs to the FKBP-type PPIase family. FKBP1 subfamily.
Contains 1 PPIase FKBP-type domain. -

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-FKBP12 antibody (ab2918)Immunohistochemistry was performed on both normal and cancer 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.

Immunocytochemistry/ Immunofluorescence - Anti-FKBP12 antibody (ab2918)ICC/IF image of ab2918 stained HepG2 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab2918, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. -

The tissue was paraformaldehyde fixed and the slides were incubated in citrate buffer for antigen retrieval and heated for 20 minutes. The tissue was incubated with ab2918 for 24 hours. The secondary antibody used was part of the DAKO ENVISON System. The picture depicts staining of nerve fibers within corporal tissue of the human penis.
