Download or read book Regulation of Drosophila Eye Development by the Transcription Factors written by Jennifer Colleen Jemc and published by . This book was released on 2007 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) First, we characterized the eye phenotypes arising from overexpression of nito. Overexpression of nito perturbs eye development and in contrast to spen, which has been shown to act as a positive effector of EGFR signaling, appears to be a negative effector of EGFR signaling during eye development. Further genetic analysis of the relationship between spen and nito in the eye suggests they function antagonistically, possibly by targeting a common set of genes for transcriptional regulation. Further analysis of SPOC family mutants and study of the functions of these proteins at a molecular level will be necessary to understand the relationship of small and large SPOC proteins and the roles of the proteins in development and disease.
