Gene Group (FlyBase)
NEPRILYSINS -
Neprilysins belong to the MEROPS M13 family of metalloproteases. The majority of proteins of this family are integral membrane proteins located at the cell surface, acting as ectoenzymes that catalyze the hydrolysis of extracellular signaling peptides. They contain all four of the conserved motifs defined as important for catalytic activity. (Adapted from FBrf0214506 and FBrf0239474.)
Protein Function (UniProtKB)
Metalloendoprotease which functions in fertility and memory formation (PubMed:24395329, PubMed:27629706). Required in the dorsal paired medial neurons and alpha/beta mushroom body neurons for the proper formation of long-term and middle-term memories (PubMed:27629706). Required in males to maximise egg-laying in female mates and is also required in females for their fertility (PubMed:24395329).

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).
