In this review, we examine the role of AUXIN BINDING PROTEIN 1 (ABP1) in mediating growth and developmental responses. ABP1 is involved in a broad range of cellular responses to auxin, acting either as the main regulator of the response, such as seen for entry into cell division or, as a fine-tuning device as for the regulation of expression of early auxin response genes. Phylogenetic analysis has revealed that ABP1 is an ancient protein that was already present in various algae and has acquired a motif of retention in the endoplasmic reticulum only recently. An evaluation of the evidence for ABP1 function according to its cellular localization supports the plasma membrane as a starting point for ABP1-mediated auxin signaling.
