Conomarphin Eu1 (P08991) Protein Card

General Information
Name Conomarphin Eu1
Alternative name(s) Conomarphin Eb1
Organism Conus eburneus
Organism diet generalist
Protein Type Wild type
Notes Mendoza et al.,2019 reported that D‐Phe13 is critical to the biological activity of conomarphins, while amino acid changes at position 10 and removal of post-translational modification in Hyp10Pro can be tolerated. They also reported that treatment of Conomarphin Eb1 in P. padulosa caused sluggishness (>0.5 nmol), with minimal exposure of foot and cephalic tentacles (>5 nmol), while elicit no effects on C.auratus and mice.
