AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

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).

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see JBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
pyr and ths show redundancy in the process of mesoderm spreading during gastrulation. pyr is required for formation of cellular protrusions during dorsolateral migration of the mesoderm and for differentiation of pericardial and cardioblast lineages. Other mesodermal lineages, however, require both ths and pyr for their consistent specification.
Loss of function mutants show loss of cardiac tissues and hindgut musculature. Misexpression of ths results in expansion of dorsal mesoderm lineages.

The genes "pyramus" and "thisbe" are named for the "heartbroken" lovers described in Ovid's Metamorphoses because the genes are linked and the mutant phenotype shows a lack of heart.
