MyBioSource.com's CD3E Polyclonal Antibody is a Rabbit Polyclonal antibody. This antibody has been shown to work in applications such as: Immunofluorescence, Immunohistochemistry, and Western Blot. The CD3E Polyclonal Antibody was generated using CD3E, and CD3e molecule as the antigen and it reacts with Human, Mouse, and Rat.
Description
When T cells encounter antigens via the T cell receptor (TCR), information about the quantity and quality of antigens is relayed to the intracellular signal transduction machinery (1). This activation process depends mainly on CD3 (Cluster of Differentiation 3), a multiunit protein complex that directly associates with the TCR. CD3 is composed of four polypeptides: zeta, gamma, epsilon and delta. Each of these polypeptides contains at least one immunoreceptor tyrosine-based activation motif (ITAM) (2). Engagement of TCR complex with foreign antigens induces tyrosine phosphorylation in the ITAM motifs and phosphorylated ITAMs function as docking sites for signaling molecules such as ZAP-70 and p85 subunit of PI-3 kinase (3,4). TCR ligation also induces a conformational change in CD3epsilon, such that a proline-region is exposed and then associates with the adapter protein Nck (5)
