Target Information

The cystatin superfamily is a well-established family of cysteine protease inhibitors.
Cystatins A and B (type 1) are mainly intracellular; cystatins C, D, E/M, F, G, S, SN, and SA are extracellular (type 2); and kininogens are type 3 cystatins which are intravascular proteins.

All true cystatins inhibit cysteine peptidases of the papain family, such as cathepsins, and some also inhibit legumain family enzymes.
Cystatin SA, S, and SN are found primarily in saliva, but can also be expressed in tears, urine, and seminal fluid.
Cystatin C is expressed in brain, thymus, ovary, epididymis, and vas deferens.
Cystatin D protects against proteinases in the oral cavity, while Cystatin E/M and F moderate inhibition of cathepsin proteins.

Fetuins, part of the cystatin superfamily, are secretable proteins influencing osteogenesis, bone resorption, insulin and hepatocyte growth factor receptor regulation, and systemic inflammation response.
High and low molecular weight kininogens inhibit thrombin- and plasmin-induced aggregation of thrombocytes.
