1. Actin interacting protein-1 (WD repeat-containing protein 1). The human homologue (606 aa) of an actin-binding protein originally identified in yeast. Induces disassembly of actin filaments in conjunction with actin depolymerizing factor/*cofilin family proteins.
2. ALG-2-interacting protein 1 (apoptosis-linked-gene-2 interacting protein 1, 868 aa), an adaptor protein that controls the production of endosomes and trafficking through the endosomal system.
