A novel Drosophila ALP/Enigma protein binds to Alpha-actinin to promote sarcomere assembly.
Z-discs define sarcomere boundaries and anchor actin filaments in muscle, yet many structural components remain uncharacterized. In this paper, we identify three new members of the Alp/Enigma family in Drosophila, including Uchmaz (CG42319), a PDZ domain-containing protein, that we characterize in detail. We used CRISP...
