Gene Summary
dalmatian (dmt) encodes a nuclear protein that localizes to centromeric heterochromatin and other polytene chromosome bands. It is required to block expression of rpr and hid during the radiation resistant stage of embryonic development, when cells become irreversibly committed to cell fate.

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).

          RNAi screen using dsRNA made from templates generated with primers directed against this gene results in chromosome misalignment on the metaphase spindle when assayed in S2 cells. This phenotype can be observed when the screen is performed with or without Cdc27 dsRNA.
