The Id protein Extramacrochaetae restrains the E protein Daughterless to regulate Notch, Rap1, and Sevenless within the R7 equivalence group of the Drosophila eye.

Biology open - 15 Aug 2024

Reddy Onteddu Venkateswara, Bhattacharya Abhishek, Baker Nicholas E

Abstract excerpt

The Drosophila Id gene extramacrochaetae (emc) is required during Drosophila eye development for proper cell fate specification within the R7 equivalence group. Without emc, R7 cells develop like R1/6 cells, and there are delays and deficits in differentiation of non-neuronal cone cells. Although emc encodes an Inhibitor of DNA-binding (Id) protein that is known to antagonize proneural bHLH protein function, no...
