NCBI Protein Information
Auxin efflux carrier family protein
NCBI Summary
Encodes a novel component of auxin efflux that is located apically in the basal cell and is involved during embryogenesis in setting up the apical-basal axis in the embryo. It is also involved in pattern specification during root development. In roots, it is expressed at lateral and basal membranes of provascular cells in the meristem and elongation zone, whereas in the columella cells it coincides with the PIN3 domain. Plasma membrane-localized PIN proteins mediate a saturable efflux of auxin. PINs mediate auxin efflux from mammalian and yeast cells without needing additional plant-specific factors. The action of PINs in auxin efflux is distinct from PGPs, rate-limiting, specific to auxins and sensitive to auxin transport inhibitors. PINs are directly involved of in catalyzing cellular auxin efflux.

UniProt Comments
Acts as a component of the auxin efflux carrier (PubMed:14614497, PubMed:20439545). Mediates the initial auxin gradient which contributes to the establishment of the apical-basal axis in early embryogenesis (PubMed:14614497).
