[Characterizing the CD3 epsilon chain from the New World primate Aotus nancymaae].

Introduction: The T-cell receptor (TCR)-associated complex, CD3 (d, g, e) and z-chains are essential transmembrane proteins for signal transduction during T cell activation and immune response, as well as during thymocyte development.

Objective: This work established the CD3epsilon-chain primary structure for the New World owl monkey Aotus nancymaae.

Materials And Methods: Total RNA was isolated from peripheral blood mononuclear cells; CD3epsilon molecule was amplified, cloned and sequenced.
