Molecular Aspect of Annelid Neuroendocrine system [PDF]

open access: yesInvertebrate Neuropeptides and Hormones: Basic Knowledge and Recent Advances, Transworld Research Network (Ed.) (2007) 19, 2007
Hormonal processes along with enzymatic processing similar to that found in vertebrates occur in annelids. Amino acid sequence determination of annelids precursor gene products reveals the presence of the respective peptides that exhibit high sequence identity to their mammalian counterparts. Furthermore, these neuropeptides exert similar physiological
