Function
FK506- and rapamycin-binding proteins (FKBPs) constitute a family of receptors for the two immunosuppressants which inhibit T-cell proliferation by arresting two distinct cytoplasmic signal transmission pathways. PPIases accelerate the folding of proteins. -
Sequence similarities
Belongs to the FKBP-type PPIase family.
Contains 1 PPIase FKBP-type domain. -
Cellular localization
Nucleus. - Information by UniProt

ab16654 specifically recognises FKBP25 (lane1), which can be blocked using the N-terminal immunizing peptide (lane2) but not the corresponding C-terminal peptide (lane3). -
Immunoprecipitation - Anti-FKBP25 antibody (ab16654)This image is courtesy of an anonymous Abreviewab16654 immunoprecipitating FKBP25 from rat PC12 whole cell lysate. A protein A matrix was used and the antibody was used at 4ug/mg of the lysate. Ab16654 was used in subsequent western blot (Lane 1). Lane 2 shows control IgG immunoprecipitate, Lane 3 shows input material.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-FKBP25 antibody (ab16654)Image courtesy of Human Protein Atlas
ab16654 staining FKBP25 in human testis, showing a distinct and strong staining pattern at cells in ductus seminiferus. Paraffin embedded human skin tissue was incubated with ab16654 (1/1000 dilution) for 30 mins at room temperature. Antigen retrieval was performed by heat induction in citrate buffer pH 6.
.
ab16654 was tested in a tissue microarray (TMA) containing a wide range of normal and cancer tissues as well as a cell microarray consisting of a range of commonly used, well characterised human cell lines. Further results for this antibody can be found at www.proteinatlas.org
