ATTECs (Targeted Protein Transport Inducing Compounds) are specifically designed to alter the intracellular location of particular proteins, thereby regulating biological responses and signaling pathways. These compounds function by recognizing specific protein targets and inducing their relocalization, consequently influencing cell functions and pathological states. The structural design of ATTECs includes targeting domains and transport-promoting domains, enabling them to transfer proteins from one cellular compartment to another. The specific localization within cells or tissues depends on the natural distribution of their target proteins. The specificity of gene expression and any associated mutations can impact the efficacy and selectivity of ATTECs, providing a novel strategy for disease treatment.
