Name :
Human CD3g/CD3gamma Protein, ECD (Extracellular Domain), Fc-fusion, Biotinylated, Recombinant
Description :
T-cell surface glycoprotein CD3 gamma chain, also known as CD3-gamma, CD3g, T3g and IMD17, 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. CD3g 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. The genes encoding the CD3 epsilon, gamma and delta polypeptides are located in the same cluster on chromosome 11. Defects in the CD3g gene are a cause of immunodeficiency 17 (IMD17), an autosomal recessive primary immunodeficiency characterized by highly variable clinical severity. Some patients have onset of severe recurrent infections in early infancy that may be lethal, whereas others may be only mildly affected or essentially asymptomatic into young adulthood. More severely affected patients may have evidence of autoimmune disease or enteropathy. The immunologic pattern is similar among patients, showing partial T-cell lymphopenia, decreased amounts of the CD3 complex, and impaired proliferative responses to T-cell receptor dependent stimuli. The phenotype in some patients is reminiscent of severe combined immunodeficiency.
