This review traces the evolutionary trajectory of split-protein systems. We begin with their foundational use in mechanistic discovery, where they first visualized viral-host interactions in living cells. We then explore their translation into practical applications, such as high-throughput drug screening and rapid point-of-care diagnostics. A step in this evolution was the development of systematic engineering platforms, dramatically accelerating the creation of novel biosensors. Finally, we discuss the latest frontier: engineering therapeutically active \"split effectors.\" By integrating principles from synthetic biology, these advanced systems can function as programmable logic gates that respond to specific viral signatures.

This gap is mainly due to challenges that researchers of this region are facing in initiating and advancing HIV cure research locally, with lesser commitment from the French-speaking countries.
