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.

              Rim promotes the accumulation of Ca[2+] channels and synaptic vesicles in the readily releasable pool at release sites of the active zone.

              RNAi generated by PCR using primers directed to CG7305 causes a cell growth and viability phenotype when assayed in Kc167 and S2R+ cells.

              dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
