The C-terminus of cryptochrome (CRY) regulates light responses in Drosophila. These include the light-dependent binding of Drosophila dCRY to the clock proteins PERIOD and TIMELESS in a yeast two-hybrid system, which we proved to be a convenient and reliable readout of the behavior of dCRY in vivo. In this study, we present a combination of in silico analysis and experimental validation in yeast, to identify novel functional motifs in the C-terminal region of dCRY. Our results suggest that linear motifs are present in this small region, which is a likely hotspot for molecular interactions. (c) 2007 Elsevier Inc. All rights reserved.

Abstract
The C-terminus of cryptochrome (CRY) regulates light responses in Drosophila. These include the light-dependent binding of Drosophila dCRY to the clock proteins PERIOD and TIMELESS in a yeast two-hybrid system, which we proved to be a convenient and reliable readout of the behavior of dCRY in vivo. In this study, we present a combination of in silico analysis and experimental validation in yeast, to identify novel functional motifs in the C-terminal region of dCRY. Our results suggest that linear motifs are present in this small region, which is a likely hotspot for molecular interactions. (c) 2007 Elsevier Inc. All rights reserved.
