---|---|---|
SC23D_ARATH | developmental stage | In floral organs, only observed in buds, pollen grains, pollen tubes and fertilized ovules (PubMed:29390074). Highly expressed in the anther tapetum at uninucleate and bicellular stages (PubMed:29390074). |
SC23D_ARATH | function | Component of the coat protein complex II (COPII) which promotes the formation of transport vesicles from the endoplasmic reticulum (ER) (By similarity). The coat has two main functions, the physical deformation of the endoplasmic reticulum membrane into vesicles and the selection of cargo molecules (By similarity). May contribute to COPII-coated vesicles formation and ER-Golgi vesicle transport (PubMed:29390074). Together with SEC23A, essential for pollen wall development and exine patterning, probably by regulating endoplasmic reticulum (ER) export of lipids and proteins (e.g. sporopollenin) necessary for pollen wall formation (PubMed:29390074). Also involved in plastid physiology in anther tapetal cells (PubMed:29390074). |
SC23D_ARATH | similarity | Belongs to the SEC23/SEC24 family. SEC24 subfamily. |
SC23D_ARATH | subcellular location | Observed at endoplasmic reticulum exit sites (ERESs), characteristic for COPII-coated vesicles localization. |
SC23D_ARATH | tissue specificity | Mostly expressed in closed floral bud, pollen and flowers, and, to a lower extent, in mature siliques, roots and leaf primordia. |
