The present disclosure provides methods and reagents useful for analyzing protein-protein interfaces such as interfaces between a presenter protein (e.g., a member of the FKBP family, a member of the cyclophilin family, or PIN1) and a target protein. In some embodiments, the target and/or presenter proteins are intracellular proteins. In some embodiments, the target and/or presenter proteins are mammalian proteins. 1. A compound comprising:(a) an FKBP binding moiety or cyclophilin binding moiety; and(b) a cross-linking group, wherein the cross-linking group is a sulfhydryl-reactive cross-linking group, an amino-reactive cross-linking group, a carboxyl-reactive cross-linking group, a carbonyl-reactive cross-linking group, or a triazole-forming cross-linking group.2. The compound of claim 1 , wherein the cross-linking moiety is a mixed disulfide claim 1 , a maleimide claim 1 , a vinyl sulfone claim 1 , a vinyl ketone claim 1 , or an alkyl chloride.3. The compound of claim 1 , wherein the interaction between the FKBP binding moiety or cyclophilin binding moiety and FKBP or cyclophilin is non-covalent.4. The compound of claim 1 , wherein the FKBP binding moiety is an FKBP binding moiety capable of binding FKBP12 claim 1 , FKBP12.6 claim 1 , FKBP13 claim 1 , FKBP25 claim 1 , FKBP51 claim 1 , FKBP52 claim 1 , or the cyclophilin binding moiety is a cyclophilin binding moiety capable of binding PP1A claim 1 , CYPB claim 1 , CYPC claim 1 , CYP40 claim 1 , CYPE claim 1 , CYPD claim 1 , NKTR claim 1 , SRCyp claim 1 , CYPH claim 1 , CWC27 claim 1 , CYPL1 claim 1 , CYP60 claim 1 , CYPJ claim 1 , PPIL4 claim 1 , PPIL6 claim 1 , RANBP2 claim 1 , or PPWD1.5. The compound of claim 1 , wherein the FKBP binding moiety or cyclophilin binding moiety is a selective FKBP or cyclophilin binding moiety.6. The compound of claim 1 , wherein the FKBP binding moiety or cyclophilin binding moiety is a non-selective FKBP or cyclophilin binding moiety.9. The compound of claim 1 , wherein the FKBP ...
