ForwardMAPPIT
In the basic lay-out of ForwardMAPPIT, the bait is fused to a signalling-deficient receptor chimera and the prey is tethered to a receptor fragment containing functional STAT3 recruitment sites. Bait-prey interaction reconstitutes a functional receptor complex which, upon ligand binding, initiates the JAK-STAT signalling cascade. For analysis of the interaction between designated protein pairs, the ForwardMAPPIT mode can be combined with a binary assay. For detecting new interactions, FACS or array screening assays are available. A new focus is on the development of FACS-based MAPPIT strategies to test virtually all possible point mutants of a protein against all its interactions that are detectable via MAPPIT for large-scale "edgetics" studies. Similar strategies are being developed to study very large mutant panels in multiple signaling assays in parallel.

- BetaMAPPIT
describes BetaMAPPIT, a variant where STAT5 is used as signalling mediator instead of STAT3 and the prey is fused to a fragment of the beta common receptor chain instead of gp130; this modification allows MAPPIT to be used in cell types not expressing high enough endogeneous STAT3 levels, e.g. hematopoietic cells
