F BOX ONLY PROTEINS -
F box only proteins (FBXO) are F box proteins which do not contain WD40 repeats or leucine-rich repeats, but may contain other domains. F box proteins are the variable substrate adapters for Skp, Cullin, F-box (SCF) E3 ubiquitin ligase complexes. (Adapted from FBrf0225076).

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).
