Immunophilins are a family of soluble cytosolic receptors capable of binding to one of two major immunosuppressant agents - cyclosporin A (CsA) (Prod. No.
ALX-380-002) or FK506 (Prod. No.
ALX-380-008). Proteins which bind FK506 are termed FK506 Binding Proteins (FKBP’s) and those which bind cyclosporin A are called cyclophilins (CyP). Both CyP:CsA and FKBP:FK506 complexes have been shown to inhibit calcineurin, a calcium and calmodulin dependent protein phosphatase which has been implicated as an important signaling enzyme in T-cell activation, providing a possible mechanism of immunosuppression by CsA and FK506.
Immunophilins function as peptidyl prolyl
cis-trans-isomerases (PPIase) whose activity is inhibited by their respective immunosuppressant compounds. As PPIase’s, 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. Prod. No.
ALX-210-236 is a polyclonal antibody that reacts with a ~51kDa protein which is found associated with the progesterone receptor. This protein is also referred to as FKBP54 and FKBP5 in the literature. This protein is predominantly expressed in murine T cells but in humans, it is abundantly expressed in numerous tissues at levels many times higher than FKBP12. The FKBP51 gene is known to be induced by glucocorticoids.
