The complex LTO1:YAE1 functions as a target specific adapter that recruits apo-RLI1 to the cytosolic iron-sulfur protein assembly (CIA) complex machinery. Forms a complex with LTO1; the complex bridges the interaction between the CIA complex and RLI1 (PubMed:23318452, PubMed:26182403). Interacts with RLI1 (PubMed:23318452, PubMed:26182403). Present with 1500 molecules/cell in log phase SD medium. Belongs to the YAE1 family.
