Western blot analysis of extracts from Jurkat (lane2, 20μg), Mouse bone tissue (lane3, 20μg), Rat spleen tissue (lane4, 20μg) and Mouse spleen tissue (lane5, 20μg) using CD3 epsilon Antibody (HY-P86568). Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/5000) and Loading control antibody (Beta Actin, HY-P80993, 1/10,000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Rabbit IgG-HRP Secondary Antibody (HY-P8001,1/10,000) was used for 1 hour at room temperature.

Immunohistochemical analysis of paraffin-embedded mouse appendix tissue using CD3 epsilon Antibody (HY-P86568, 1/1000). The section was pretreated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 8 minutes. The tissues were blocked with quick block buffer for 0.5 hours at room temperature, washed with PBS and PBST, and then incubated with the primary antibody overnight at 4℃. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Background

Function
CD3 epsilon is a 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. 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. Also participates in internalization and cell surface down-regulation of TCR-CD3 complexes via endocytosis sequences present in CD3E cytosolic region. In addition to its role as a TCR coreceptor, it serves as a receptor for ITPRIPL1. Ligand recognition inhibits T-cell activation by promoting interaction with NCK1, which prevents CD3E-ZAP70 interaction and blocks the ERK-NFkB signaling cascade and calcium influx[1][2][3][4].

Subunit
The TCR-CD3 complex is composed of a CD3D/CD3E and a CD3G/CD3E heterodimers that preferentially associate with TCRalpha and TCRbeta, respectively, to form TCRalpha/CD3E/CD3G and TCRbeta/CD3G/CD3E trimers. In turn, the hexamer interacts with CD3Z homodimer to form the TCR-CD3 complex. Alternatively, TCRalpha and TCRbeta can be replaced by TCRgamma and TCRdelta. Interacts with CD6 (PubMed:15294938). Interacts (via Proline-rich sequence) with NCK1; the interaction is ligand dependent but independent of tyrosine kinase activation (PubMed:12110186, PubMed:15972658, PubMed:38614099). Interacts with NUMB; this interaction is important for TCR-CD3 internalization and subsequent degradation (PubMed:26507128)
