abstract = {20-hydroxyecdysone (20E) and juvenile hormone (JH)
signaling pathways interact to regulate insect development.
Recently,two proteins, a calponin-like Chd64 and
immunophilin FKBP39 have been found to play a pivotal role
in the cross-talkbetween 20E and JH, although the molecular
basis of interaction remains unknown. The aim of this work
was to identify thestructural features that would provide
understanding of the role of Chd64 in multiple and dynamic
complex that cross-linksthe signaling pathways. Here, we
demonstrate the results of in silico and in vitro analyses
of the structural organization ofChd64 from Drosophila
melanogaster and its homologue from Tribolium castaneum.
Computational analysis predicted theexistence of disordered
regions on the termini of both proteins, while the central
region appeared to be globular, probablycorresponding to the
calponin homology (CH) domain. In vitro analyses of the
hydrodynamic properties of the proteinsfrom analytical
size-exclusion chromatography and analytical
ultracentrifugation revealed that DmChd64 and TcChd64 hadan
asymmetrical, elongated shape, which was further confirmed
by small angle X-ray scattering (SAXS). The Kratky
plotindicated disorderness in both Chd64 proteins, which
could possibly be on the protein termini and which would
give rise tospecific hydrodynamic properties. Disordered
tails are often involved in diverse interactions. Therefore,
it is highly possiblethat there are intrinsically disordered
regions (IDRs) on both termini of the Chd64 proteins that
serve as platforms formultiple interaction with various
partners and constitute the foundation for their regulatory
function.},
