Endosomal adaptor proteins are important regulators of signaling pathways
underlying many biological processes. These adaptors can integrate signals from
multiple pathways via localization to specific endosomal compartments, as well as
through multiple protein-protein interactions. One such adaptor protein that has
been implicated in regulating signaling pathways is the adaptor protein
containing a pleckstrin homology (PH) domain, phosphotyrosine-binding (PTB)
domain, and leucine zipper motif 1 (APPL1). APPL1 localizes to a subset of
Rab5-positive endosomes through its Bin-Amphiphysin-Rvs and PH domains, and it
coordinates signaling pathways through its interaction with many signaling
receptors and proteins through its PTB domain. This review discusses our current
understanding of the role of APPL1 in signaling and trafficking, as well as
highlights recent work into the function of APPL1 in cell migration and adhesion.
