$525.00 – $1,750.00

Summary

Expression: HEK293
Functional: Yes (ELISA)
Amino Acid Range: Leu26-Pro247

SKU: 4766parent Categories: proteins, Recombinant proteins Tag: active proteins

Weight	1 lbs
Dimensions	9 × 5 × 2 in
express system	HEK293
product tag	C-His-Avi
purity	> 95% as determined by Tris-Bis PAGE
background	B7-1 and B7-2 are homologous costimulatory ligands expressed on the surface of antigen presenting cells (APCs). Binding of these molecules to the T cell costimulatory receptors, CD28 and CTLA-4, is essential for the activation and regulation of T cell immunity. B7-1 and B7-2 do not form hetero-oligomers, underscoring the biological relevance of dimeric and monomeric state of B7-1 and B7-2, respectively.
molecular weight	The protein has a predicted MW of 28.2 kDa. Due to glycosylation, the protein migrates to 55-70 kDa based on Tris-Bis PAGE result.
available size	100 µg, 500 µg
endotoxin	Less than 1EU per μg by the LAL method.

Protein names T-lymphocyte activation antigen CD86 (Activation B7-2 antigen) (B70) (BU63) (CTLA-4 counter-receptor B7.2) (FUN-1) (CD antigen CD86)
Gene names CD86,CD86 CD28LG2
Mass 9606Da
Function Receptor involved in the costimulatory signal essential for T-lymphocyte proliferation and interleukin-2 production, by binding CD28 or CTLA-4. May play a critical role in the early events of T-cell activation and costimulation of naive T-cells, such as deciding between immunity and anergy that is made by T-cells within 24 hours after activation (PubMed:7527824). Also involved in the regulation of B cells function, plays a role in regulating the level of IgG(1) produced. Upon CD40 engagement, activates NF-kappa-B signaling pathway via phospholipase C and protein kinase C activation (By similarity).; [Isoform 2]: Interferes with the formation of CD86 clusters, and thus acts as a negative regulator of T-cell activation.; (Microbial infection) Acts as a receptor for adenovirus subgroup B.
Subellular location Cell membrane; Single-pass type I membrane protein.
Tissues Expressed by activated B-lymphocytes and monocytes.
Structure Homodimer. Interacts with MARCH8. Interacts (via cytoplasmic domain) with PHB1 and PHB2; the interactions increases after priming with CD40 (By similarity).; (Microbial infection) Interacts with adenovirus subgroup b fiber protein.; (Microbial infection) Interacts with Orthopoxvirus OPG038/M2 protein, inhibiting the interaction with CTLA4 and CD28.
Post-translational modification Polyubiquitinated; which is promoted by MARCH8 and results in endocytosis and lysosomal degradation.
