The molecular structure of the hormone has been characterized rather recently. Bursicon is a 30 kDa neurohormone heterodimeric protein which is encoded by CG13419 gene and made of two cysteine knot subunits, Burs-α and Burs-β. It is nondialyzable and loses its activity in alcohol, acetone, some … See more Bursicon (from the Greek bursikos, pertaining to tanning) is an insect hormone which mediates tanning in the cuticle of adult flies. See more Bursicon is found in different insects and considered to be unspecific. It is produced by median neurosecretory cells in the brain, circulates in blood and stored in corpora cardiaca. The structure of the protein has been investigated well in … See more Bursicon plays a very important role in insect wing expansion during the last step of metamorphosis: maturation of the wing. At this time, the newly emerged adult removes dead cells of See more Firstly, mutants of Drosophila melanogaster that lack bursicon gene can not spread their wings after eclosion. Secondly, the elongated abdomen shape of a newly eclosed fly remains for a much longer period of time.

WebCitation 18 The neurohormone Bursicon is the crucial hormone responsible for the coordination of those final steps of adult ecdysis. The molecular identity of Bursicon remained unknown for decades until the CG13419 locus (called bursicon or burs, hereafter called burs-α) was identified to be responsible for wing inflation. Citation 6 WebAug 31, 2010 · Bursicon hormone has been shown to activate the rickets receptor, by increasing downstream cAMP activity [7, 8], completing the link between hormone signaling and post-eclosion development. Establishing a role for the bursicon signaling pathway preceding eclosion has been more difficult to demonstrate, primarily because rk 1 and rk …
