Euarchontan Opsin Variation Brings New Focus to Primate Origins.

abstract：:Signaling peptides enable communication between cells, both within and between individuals, and are therefore key to the control of complex physiological and behavioral responses. Since their small sizes prevent direct transmission to secretory pathways, these peptides are often produced as part of a larger polyprotei...
