Gene Group (FlyBase)
Protein Family (UniProt)
Belongs to the SEC6 family. (Q9V8K2)
Summaries
Gene Group (FlyBase)
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, Q9V8K2)
Summary (Interactive Fly)

component of the exocyst which tethers secretory vesicles to specific plasma membrane sites - a Rab11 effector that facilitates protein transport to the apical rhabdomere in Drosophila photoreceptor cells - regulates E-Cadherin trafficking from recycling endosomes to the plasma membrane

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.

Testis-specificity index

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).
