Model confidence (pLDDT)

The mean pLDDT of this model is 47.4 (very low overall). pLDDT is AlphaFold's per-residue confidence score from 0 to 100. In MolViewer, choose the B-factor color scheme to color the model by pLDDT, because AlphaFold stores it in the B-factor column.

What pLDDT means and how to read it

Function

Forms a complex with sd/scalloped that acts as a transcriptional activator regulating gene expression during wing development (PubMed:11112330, PubMed:12702681, PubMed:14526388, PubMed:9799424, PubMed:9869635, PubMed:9869643). Binding to sd switches the DNA target selectivity of sd to recognize a distinct set of target enhancers (PubMed:11546746). Together with sd regulates expression of Bx/Beadex/dLMO, which in turn regulates the activity of ap/apterous involved in driving cellular proliferation and dorsoventral (D/V) boundary formation in wing imaginal discs (PubMed:12485165, PubMed:16950871). Together with sd involved in regulating cell adhesion properties involved in the separation of…

Subunit structure

Interacts (via Ser-rich sd binding domain) with sd (via C-terminus); the interaction is direct (PubMed:12702681, PubMed:12782275, PubMed:14526388, PubMed:33060790, PubMed:9799424, PubMed:9869635, PubMed:9869643). Interacts with Dhfr (PubMed:14526388)
