CD3

Cluster of differentiation 3

CD3 (cluster of differentiation 3) is a protein complex and T cell co-receptor that is involved in activating both the cytotoxic T cell (CD8+ naive T cells) and T helper cells (CD4+ naive T cells). It is composed of four distinct chains. In mammals, the complex contains a CD3γ chain, a CD3δ chain, and two CD3ε chains. These chains associate with the T-cell receptor (TCR) and the CD3-zeta (ζ-chain) to generate an activation signal in T lymphocytes. The TCR, CD3-zeta, and the other CD3 molecules together constitute the TCR complex.

    		Inhibitor ≥99%
    Xaluritamig (AMG-509) is a bispecific T cell engager and cytolytic agent with a Kd of 27.6 nM for human CD3ε. Xaluritamig binds to CD3ε via an anti-CD3 single-chain variable fragment (scFv) domain, and to STEAP1 via a bispecific anti-STEAP1 antigen-binding fragment (Fab) domain, thereby recruiting and activating T cells and forming a bridge between T cells and STEAP1-expressing cancer cells. Xaluritamig induces T cell-mediated redirected cytotoxicity, tumor cell lysis, cytokine release, CD8+ T cell activation and expansion, as well as tumor stasis or regression. Xaluritamig contains an Fc domain with no effector function, which prolongs serum half-life, exhibits only minimal activity against cells with low STEAP1 expression and normal cells, and shows extremely low target-related off-tumor toxicity in cynomolgus monkeys. Xaluritamig is used in STEAP1×CD3 XmAb 2+1 immunotherapy and in research on metastatic castration-resistant prostate cancer and Ewing sarcoma.
