Name :
Human CD3d/CD3delta Protein, ECD (Extracellular Domain), Fc-fusion, Biotinylated, Recombinant
Description :
T-cell surface glycoprotein CD3 delta chain, also known as CD3-delta, CD3d, T3d and IMD19, is a single-pass type I transmembrane protein. CD3d contains 1 Ig-like (immunoglobulin-like) domain in the extracellular region and 1 cytoplasmic ITAM (immune tyrosine activation motif) domain. CD3d is part of the T-cell receptor (TCR)/CD3 complex and is involved in T-cell development and signal transduction. The TCR/CD3 complex of T-lymphocytes consists of either a TCR alpha/beta or TCR gamma/delta heterodimer co-expressed at the cell surface with the invariant subunits of CD3 labeled gamma, delta, epsilon, zeta, and eta. The TCR/CD3 complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways leading to the activation of T cells. Defects in the CD3d gene cause severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-positive/NK-cell-positive (SCIDBNK) and immunodeficiency 19 (IMD19). The genes encoding the CD3 epsilon, gamma and delta polypeptides are located in the same cluster on chromosome 11.

Uniprot Entry :
P04234
Construct Details :
The recombinant human CD3d-Fc fusion is expressed as a 323 amino acid protein consisting of Phe22 – Gly106 region of CD3d (Uniprot Accession #P04234) and a C-terminal Fc from human IgG1, which exists as a dimer under non-reducing conditions.
