An 11-ketotestosterone induced kidney-secreted protein: the nest building glue from male three-spined stickleback, Gasterosteus aculeatus

Abstract

In male three-spined sticklebacks, Gasterosteus aculeatus, the kidney hypertrophies during the breeding season and produces a glue which is used in nest-building. This hypertrophy is androgen dependent with 11-ketotestosterone (11 KT) being most effective. The aim of the present study was to characterize the protein composition of this glue. Threads of glue… (More)
