Gene Summary
Calmodulin-binding transcription activator (Camta) encodes a Ca[2+]-responsive transcription factor that either binds directly to DNA sequences containing a CGCG core motif or functions as a coactivator of NKX2 transcription factors. It mediates various physiological functions, including the regulation of visual signal transduction, memory formation and cell survival. [Date last reviewed: 2019-03-07] (FlyBase Gene Snapshot)

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.

              Isolated in a screen for aberrant courtship song.

              Mutant males are characterised by low mating success, aberrant courtship song patterns and poor flying ability.
