ASP39_ARATH | developmental stage | In flowers, expressed in the pollen and growing pollen tubes (PubMed:27872247). During microspore development, observed expressed from tetrad to tricellular pollen (PubMed:27872247). Also present in young siliques and developing ovules (PubMed:27872247). |
ASP39_ARATH | function | Displays aspartic proteolytic activity (PubMed:27872247). Together with A36, contributes to pollen and ovule development, including the apical cell wall constitution of the growing pollen tubes (PubMed:27872247). |
ASP39_ARATH | similarity | Belongs to the peptidase A1 family. |
ASP39_ARATH | subcellular location | 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). |
ASP39_ARATH | tissue specificity | Highly expressed in pollen and pollen tubes (PubMed:27872247). Mostly expressed in inflorescence, flowers and siliques, and barely in leaves and seedlings (PubMed:27872247). |
