resilin in British English (ˈrɛzəˌlɪn) nouna highly elastic substance consisting of protein chains, found in the exoskeletons of various insects Examples of 'resilin' in a sentenceresilin The predicted protein was found to be related to the pro-resilin family of cuticular proteins.Resilin functions as an elastic spring that demonstrates extraordinary extensibility and elasticity.Nitrogen concentrations in insect exoskeletons appear to increase as abundances of resilin and other fluorescent, elastic proteins increase.Within the exoskeleton structures, resilin commonly forms composites together with other proteins and/or chitin fibres.In the last decades, numerous exoskeleton structures with large proportions of resilin and various resilin functions have been described.The functional significance of resilin joints may shed light on the evolutionary relationship between morphological and structural hind wing properties.They are built of chitinous cuticle and the rubber-like protein, resilin, which fluoresces bright blue when illuminated with ultra-violet light.The composite structure therefore, combines the stiffness of the chitinous cuticle with the elasticity of resilin. |
