Cibisatamab Biosimilar Bispecific Antibody (CEA × CD3) for Research
Anti-CEACAM5/CD66e;CD3E therapeutic antibody (Pre-made Cibisatamab biosimilar,Bispecific mAb with Domain Crossover, Anti-CEA;T3E/TCRE/IMD18 Antibody) is a biosimilar expressed by mammalian cell line as a benchmark reference therapeutic antibody for biological drug disovery items including cell culture, assay development, animal model development, PK/PD model development (Pharmacokinetics & Pharmacodynamic) and mechanism of action (MOA) research.
Cibisatamab, an investigational drug, is a bispecific antibody, which means it binds to two different proteins: one called CEACAM5 on the surface of some colorectal cancer cells and another on T cells called CD3.

About target - CD3E
1. Protein T-cell surface glycoprotein CD3 epsilon chain
2. Gene CD3E
3. Organism Homo sapiens (Human)
Function
Part of the TCR-CD3 complex present on T-lymphocyte cell surface that plays an essential role in adaptive immune response. When antigen presenting cells (APCs) activate T-cell receptor (TCR), TCR-mediated signals are transmitted across the cell membrane by the CD3 chains CD3D, CD3E, CD3G and CD3Z. All CD3 chains contain immunoreceptor tyrosine-based activation motifs (ITAMs) in their cytoplasmic domain. Upon TCR engagement, these motifs become phosphorylated by Src family protein tyrosine kinases LCK and FYN, resulting in the activation of downstream signaling pathways (PubMed:2470098).
In addition of this role of signal transduction in T-cell activation, CD3E plays an essential role in correct T-cell development. Initiates the TCR-CD3 complex assembly by forming the two heterodimers CD3D/CD3E and CD3G/CD3E. Participates also in internalization and cell surface down-regulation of TCR-CD3 complexes via endocytosis sequences present in CD3E cytosolic region (PubMed:10384095, PubMed:26507128).
