auxin efflux carrier (TC 2.A.69.1) family

DESCRIPTION

Also known as PIN8_ARATH, PIN8, PIN5. Component of the intracellular auxin-transport pathway in the male gametophyte (PubMed:20439545, PubMed:22540348). Involved in the regulation of auxin homeostasis in pollen (PubMed:22540348). Involved in the efflux of auxin from the endoplasmic reticulum into the cytoplasm (PubMed:22760640). PIN5 and PIN8 may have an antagonistic/compensatory activity (PubMed:22760640, PubMed:22990451). Involved in the control of vein patterning (PubMed:23437008, PubMed:24304505). Redundantly with PIN6, inhibits the vein-formation-promoting functions of PIN5 (PubMed:26560462). PIN5, PIN6, and PIN8 control vein network geometry, but they are expressed in mutually exclusive domains of leaf vascular cells (PubMed:26560462).
