Gene Summary
zydeco (zyd) encodes a potassium-dependent sodium/calcium exchanger found in cortex glia. It is thought to serve as a key calcium export pathway to control calcium oscillations that occur in membrane microdomains of the glial cell. [Date last reviewed: 2019-03-21] (FlyBase Gene Snapshot)

Gene Group (FlyBase)
SLC24 FAMILY OF POTASSIUM-DEPENDENT SODIUM/CALCIUM EXCHANGERS -
Solute carrier family 24 (SLC24) transmembrane transporters are potassium-dependent sodium/calcium exchangers, which use both the inward sodium gradient and the outward potassium gradient to release calcium. (Adapted from FBrf0111900).

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).
