FKBP

FKBP (FK506-binding protein) is one of two major immunophilins and most of FKBP family members bind FK506 and show peptidylprolyl cis/trans isomerase (PPIase) activity. Small size FKBP family members contain only FK506-binding domain, while FKBPs with large molecular weights possess extra domains such as tetratricopeptide repeat domains, calmodulin binding and transmembrane motifs. FKBPs are involved in several biochemical processes including protein folding, receptor signaling, protein trafficking and transcription. FKBP family proteins play important functional roles in the T-cell activation, when complexed with their ligands.

FK506-binding proteins 1a and 1b (FKBP1a/1b) are immunophilin proteins that bind the immunosuppressant agent FK506 and AY 22989. FKBP12 is a ubiquitous abundant protein that acts as a receptor for FK506, binds tightly to intracellular calcium release channels and to the transforming growth factor β (TGF-β) type I receptor.

GC73491 RapaBlock

ZZY05-092
RapaBlock is a potent, non-immunosuppressive and brain-impermeable FKBP12 ligand.
GC33699 SAFit1 SAFit1 is a FK506 binding protein 51 (FKBP51)-specific inhibitor with a Ki of 4±0.3 nM.
GC34093 SAFit2 An FKBP51 inhibitor
GC38060 Shield-1

Shld1
Shield-1 (Shld1) is a specific, cell-permeant and high-affinity ligand of FK506-binding protein-12 (FKBP), and reverses the instability by binding to mutated FKBP (mtFKBP), allowing conditional expression of mtFKBP-fused proteins.
GC44899 SLF

Synthetic Ligand of FKBP
FK-506 is a potent immunosuppressant that forms a high affinity complex (Ki = 0.2 nM) with FK-506 binding protein 12 (FKBP12).
GC16233 Tacrolimus (FK506)

Tacrolimus

Tacrolimus (FK506), a macrolide antibiotic with potent immunosuppressive effects was isolated from Streptomyces tsukubaensis and has been previously used to prevent allograft and for treatment of autoimmune disorders in humans.
GC17995 Tacrolimus monohydrate immunosuppressive drug
GC33200 Target Protein-binding moiety 13

PROTAC FKBP12-binding moiety 1
Target Protein-binding moiety 13 (PROTAC FKBP12-binding moiety 1) is a synthetic ligand for FKBP (SLF). Target Protein-binding moiety 13 (PROTAC FKBP12-binding moiety 1) can be used in the synthesis of PROTACs.
GC66370 Zapalog Zapalog is a photocleavable small-molecule heterodimerizer that can be used to repeatedly initiate, and instantaneously terminate, a physical interaction between two target proteins. Zapalog dimerizes any two proteins tagged with the FKBP and DHFR domains until exposure to light causes its photolysis.
