Biotinylated Cynomolgus / Rhesus macaque CTLA-4 Protein, Avitag™,His Tag

Biotinylated Cynomolgus / Rhesus macaque CTLA-4, Avitag,His Tag (CT4-C82E5) is expressed from human 293 cells (HEK293). It contains AA Ala 37 - Ser 160 (Accession # G7PL88-1). In the region Ala 37 - Ser 160, the AA sequence of Cynomolgus and Rhesus macaque CTLA-4 are homologus.

Dodatkowe informacje:

CTLA-4 (Cytotoxic T-Lymphocyte Antigen 4) is also known as CD152 (Cluster of differentiation 152), is a protein receptor that downregulates the immune system. CTLA4 is a member of the immunoglobulin superfamily, which is expressed on the surface of Helper T cells and transmits an inhibitory signal to T cells. The protein contains an extracellular V domain, a transmembrane domain, and a cytoplasmic tail. Alternate splice variants, encoding different isoforms. CTLA4 is similar to the T-cell co-stimulatory protein, CD28, and both molecules bind to CD80 and CD86, also called B7-1 and B7-2 respectively, on antigen-presenting cells. CTLA4 transmits an inhibitory signal to T cells, whereas CD28 transmits a stimulatory signal. Intracellular CTLA4 is also found in regulatory T cells and may be important to their function. Fusion proteins of CTLA4 and antibodies (CTLA4-Ig) have been used in clinical trials for rheumatoid arthritis.

Inne:

This protein carries an Avi tag (Avitag™) at the C-terminus, followed by a polyhistidine tag. The protein has a calculated MW of 15.9 kDa. The protein migrates as 20-26 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
