    Western blot analysis of extracts from Jurkat(lane 2(15μg) or lane 3(30μg)) and Hela(lane 4(15μg) or lane 5(30μg)) using FKBP51(HY-P80401) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% BSA in TBST for 2 hour at room temperature. The primary antibody (HY-P80401, 1/1000) and Loading control antibody (GAPDH, HY-P80954, 1/3000) was used in 5% BSA in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (HY-P8004/HY-P8001, 1/10,000) was used for 1 hour at room temperature.
  • Experimental Validation Results for FKBP51 Antibody (YA433)
    Western blot analysis was performed on protein extracts (25 μg) from HeLa (lane 2), Jurkat (lane 3), HepG2 (lane 4), 293T (lane 5), and THP-1 (lane 6) using FKBP51 antibody. Proteins were transferred onto a 0.45 μm PVDF membrane using the Trans-Blot® Turbo™ system for 13 min. The membrane was then blocked with 5% nonfat milk in TBST (HY-K1025) for 1 h at room temperature. The primary antibody (1:1000) and loading control antibody GAPDH Antibody (HRP) (HY-P80954A) (1:5000) were diluted in 5% nonfat milk in TBST and incubated with the membrane overnight at 4°C. After washing, the membrane of primary antibody was incubated with HRP-conjugated goat anti-rabbit/mouse IgG secondary antibody (HY-P8001/HY-P8004) (1:5000) diluted in 5% nonfat milk in TBST for 1 h at room temperature. Protein bands were visualized using an Ultra High Sensitivity ECL detection kit (HY-K1005).

Then stained with the primary antibody at 1/100 dilution for an hour at 4℃. AF488-conjugated Goat Anti-Rabbit IgG H&L (HY-P8002) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃.

Background

  • Function

    FKBP51, encoded by FKBP5, is an Hsp90-associated immunophilin co-chaperone that regulates glucocorticoid receptor sensitivity and steroid receptor signaling[1]. Mechanistically, FKBP51 integrates into GR:Hsp90 complexes and antagonizes FKBP52-dependent potentiation of glucocorticoid receptor activity[2]. In cancer signaling models, FKBP51 acts as an Akt-PHLPP scaffold and promotes Akt dephosphorylation, linking FKBP51 biology to chemotherapy response research[3]. In stress-related disease studies, FKBP5 polymorphisms associate with antidepressant response, depressive episode recurrence, and childhood-abuse-dependent PTSD symptom risk[4][5]. Compared with FKBP52, FKBP51 remains a key isoform because selective ligand design must overcome their conserved FK1 binding domains and opposing GR functions[2][6]. For experimental applications, SAFit1 and SAFit2 provide selective FKBP51 inhibition through induced fit, supporting isoform-focused studies of stress behavior, neuroendocrine feedback, and target engagement[6][7].- FKBP51 research should prioritize GR:Hsp90 regulation, FKBP52 contrast, and stress-related experimental models. - SAFit-class inhibitors enable isoform-selective FKBP51 perturbation but require careful probe validation.

  • Subunit

    Part of a heteromultimeric cytoplasmic complex with HSP90AA1, HSPA1A/HSPA1B and steroid receptors. Upon ligand binding dissociates from the complex and FKBP4 takes its place (By similarity). Interacts with functionally mature heterooligomeric progesterone receptor complexes along with HSP90 and TEBP (PubMed:7693698). Interacts with NR3C1 (By similarity). Interacts with Akt/AKT1 and PHLPP1; enhancing dephosphorylation and subsequent activation of Akt/AKT1 (PubMed:28147277). Interacts with IFI44L; this interaction modulates the kinase activity of IKBKB and IKBKE (PubMed:31434731). Interacts with IKBKB and IKBKE (PubMed:26101251, PubMed:31434731)
