GRP19_ARATH | developmental stage | In flowers, present in the anther tapetum early in anther development and later in the pollen coat (PubMed:11929861, PubMed:26305561). Upon tapetum degeneration, associated with tapetosomal debris 'in transit' to the pollen cell wall in the anther locule (PubMed:26305561). |
GRP19_ARATH | function | Lipid-binding oleosin involved in anther tapetum development, especially for the physiology of tapetosomes (PubMed:26305561). Also implicated in the formation of pollen coat (PubMed:26305561). |
A8MSB7_ARATH B3H6L6_ARATH GRP19_ARATH | similarity | Belongs to the oleosin family. |
GRP19_ARATH | subcellular location | Surface of oil bodies (By similarity). Oleosins exist at a monolayer lipid/water interface (By similarity). Associated with discrete organelles within the anther tapetum called tapetosomes and with a network of structures previously described as fibrils or 'strings of beads' (PubMed:26305561). |
GRP19_ARATH | tissue specificity | Present in pollen (at protein level) (PubMed:11431566, PubMed:26305561). Inflorescence-specific expression, especially in flowers florets (PubMed:11929861, PubMed:14739246). |
