EXOCYST -
The exocyst complex is composed of eight proteins. It is involved tethering secretory vesicles to the plasma membrane and may regulate other aspects of intracellular trafficking such as SNARE assembly, cytokinesis and endocytic recycling. The exocyst complex is a member of the Complex Associated with Tethering Containing Helical Rods (CATCHR) family. (Adapted from FBrf0219543).
Protein Function (UniProtKB)
Component of the exocyst complex involved in the docking of exocytic vesicles with fusion sites on the plasma membrane.
(UniProt, Q9VDE6)
Summary (Interactive Fly)

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

          S2 cells treated with dsRNA directed against sec15 show normal binding but significantly decreased internalization of E.coli and S.aureus in a phagocytosis assay.

          dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.

          Additional comments

          FlyBase curator comment: the insertion in the "d11525" Exelixis line (P{XP}rtetd11525) was originally assigned to the sec15 gene in FBrf0179797, resulting in the "sec15d11525" (FBal0158687) allele. However, FBrf0184340 shows that the insertion is actually within rtet.
