UNCLASSIFIED CLASS C GPCRs -
This group comprises orphan Class C GPCRs that do not classify under other groups in FlyBase.
Summary (Interactive Fly)

G-protein coupled receptor - gastrulation - deformation of mesodermal and ectodermal cells - activated by the ligand Folded gastrulation - acts along with another GPCR, Mist, to activate the small GTPase Rho1, and the kinase Rok - regulates differential Rho1 and Myosin II activation

Structure
Protein 3D structure   (Predicted by AlphaFold)   (AlphaFold entry M9ND25)

If you don't see a structure in the viewer, refresh your browser.
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).

            Nomenclature comments

            FlyBase curator comment: 'CG31660' was initially named 'pog' in FBrf0208913, but FBrf0231092 shows that this was based on an incorrect association of CG31660 with the mutant 'pog[1]'. FBrf0231092 renames 'CG31660'/'pog' to 'smog'.
