Protein transport protein SEC23; Component of the coat protein complex II (COPII) which promotes the formation of transport vesicles from the endoplasmic reticulum (ER). The coat has two main functions, the physical deformation of the endoplasmic reticulum membrane into vesicles and the selection of cargo molecules; Belongs to the SEC23/SEC24 family. SEC23 subfamily.

Secretory 24AB, isoform A; Zinc ion binding; signal sequence binding. It is involved in the biological process described with: COPII-coated vesicle cargo loading; intracellular protein transport.

Protein SEC13 homolog; Functions as a component of the nuclear pore complex (NPC) and the COPII coat (By similarity). At the endoplasmic reticulum, SEC13 is involved in the biogenesis of COPII-coated vesicles (By similarity). Recruited to transcriptionally active chromatin at the time of transcription initiation by RNA polymerase II. Required for proper expression of ecdysone-responsive genes such as Eip74EF and Eip75B during larval development. Required for reactivation of transcription after heat shock. Required for nuclear import of phosphorylated Mad via importin msk. Has no role i [...]

Secretory 16 (Sec16) encodes a protein involved in the organization of endoplasmic reticulum exit sites. It contributes to stress response to amino-acid starvation, during which it mediates the formation of both Sec bodies and stress granules.

Secretory 24CD (Sec24CD) encodes a subunit of the coat protein complex of COPII vesicles, which transport cargo from the endoplasmic reticulum to the Golgi apparatus. It is essential for export of membrane and secreted proteins from the endoplasmic reticulum. It is involved in epithelial morphogenesis and differentiation.

FI09914p; GTPase activator activity; Sar guanyl-nucleotide exchange factor activity; GTPase binding. It is involved in the biological process described with: cell morphogenesis; regulation of COPII vesicle coating; protein secretion.

Coatomer subunit alpha; The coatomer is a cytosolic protein complex that binds to dilysine motifs and reversibly associates with Golgi non-clathrin- coated vesicles, which further mediate biosynthetic protein transport from the ER, via the Golgi up to the trans Golgi network.

Phosphatidic Acid Phospholipase A1 (PAPLA1) encodes a protein required for the endoplasmic reticulum to Golgi trafficking of a family of G-protein coupled receptors.

Transport and Golgi organization protein 1; Required for protein secretion. May participate in cargo loading by binding to COPII coat subunits and guiding SH3-bound proteins into a growing carrier. At basal transitional ER sites in follicle epithelial cells, mediates the exit of basal membrane protein such as vkg, LanB1 and Trol, from the endoplasmic reticulum (ER) to basal Golgi clusters.
