Identification and localization of proteins associated with biomineralization in the iron deposition vesicles of honeybees (Apis mellifera). [PDF]

PLoS ONE, 2011
Honeybees (Apis mellifera) form superparamagnetic magnetite to act as a magnetoreceptor for magnetoreception. Biomineralization of superparamagnetic magnetite occurs in the iron deposition vesicles of trophocytes.
