May act as a scaffolding protein that links PKA to components of the exocytosis machinery, thus facilitating exocytosis, including insulin release. (856 aa) |
| | Rab26 | Ras-related protein Rab-26; The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes. Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to membranes different set of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion. Mediates transport of ADRA2A and ADRA2B from the Golgi to the cell membrane. Plays a role in the maturation of zymogenic granules and in pepsinogen secretion in the stomach (By similari [...] (260 aa) |
| | Vps13b | Vacuolar protein sorting-associated protein 13B; May be involved in protein sorting in post Golgi membrane traffic; Belongs to the VPS13 family. (3993 aa) |
| | Zp3r | Zona pellucida sperm-binding protein 3 receptor; Binds to ZP3 glycoprotein in egg zona pellucida. Probably involved in interactions between sperm acrosome and egg zona pellucida during and immediately following the acrosome reaction. (579 aa) |
