(11) The predicted protein product of the lyl-1 gene contains a potential helix-loop-helix DNA binding motif also found in several proteins involved in the control of cellular proliferation and differentiation: all members of the Myc family, MyoD1, myogenin, the Drosophila achaete-scute, twist, and daughterless proteins, and two recently described immunoglobulin enhancer binding proteins.
(12) According to these and previous data, the AS-C is organized, distally to proximally, as follows: the achaete region, with most of its DNA (10 kb) located upstream from the putative achaete (T5) gene; an intermediate region, approximately 18 kb long, whose deletion only weakly affects the scute function; and the scute region, with most of the DNA critical for its function extending 4-5 kb upstream and 50 kb downstream of the putative scute (T4) gene.
(13) Essentially, the double alterations of yellow and scute phenotypes constitute more than 40% of all derivatives.

(18) The deduced amino acid sequence of clone Myf-5 reveals a region which is highly similar to myc proteins and the developmental factors from Drosophila encoded by the achaete scute locus and the twist gene.
(19) We have confirmed this model by showing that misexpression of the achaete-scute T4 gene induces ectopic Sxl expression and male-specific lethality, confirming that achaete-scute T4 is the sisterless-b counting element.
(20) In the mutants, neuronal precursor cells do not differentiate, suggesting that Hairless might be involved in specifying or realizing neuronal fate in the fly, similar to the 'pro-neural' genes of the achaete-scute complex.
