| Subcellular Location | SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:27872247}; Lipid-anchor, GPI-anchor {ECO:0000255}. Cytoplasm, cytosol {ECO:0000269|PubMed:27872247}. Note=Displays punctate cytosolic localization and colocalizes with the GPI-anchored protein COBL10 at the plasma membrane and in the cytosol (PubMed:27872247). In pollen grains, mainly present at the plasma membrane and in reticular structures in the cytosol (PubMed:27872247). In pollen tubes, exhibits a punctate localization in the cytosol and occurs weakly at the plasma membrane (PubMed:27872247). {ECO:0000269|PubMed:27872247}. |
