Protein: ABC transporter G family member 31 (ABC transporter ABCG.31) (AtABCG31) (Pleiotropic drug resistance protein 3) (AtPDR3) (Q7PC88)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Together with ABCG25, export abscisic acid (ABA) from the endosperm to deliver it to the embryo via ABCG30 and ABCG40-mediated import to suppress radicle extension and subsequent embryonic growth. Together with ABCG9, involved in pollen coat deposition of steryl glycosides required for pollen fitness. May be a general defense protein (By similarity).
Subcellular location: Cell membrane {ECO:0000269|PubMed:24474628, ECO:0000269|PubMed:26334616}; Multi-pass membrane protein {ECO:0000255}.
