Rabbit Anti-CD86/FITC Conjugated antibody
background:
This gene encodes a type I membrane protein that is a member of the immunoglobulin superfamily. This protein is expressed by antigen-presenting cells, and it is the ligand for two proteins at the cell surface of T cells, CD28 antigen and cytotoxic T-lymphocyte-associated protein 4. Binding of this protein with CD28 antigen is a costimulatory signal for activation of the T-cell. Binding of this protein with cytotoxic T-lymphocyte-associated protein 4 negatively regulates T-cell activation and diminishes the immune response. Alternative splicing results in several transcript variants encoding different isoforms.[provided by RefSeq, May 2011].
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. Isoform 2 interferes with the formation of CD86 clusters, and thus acts as a negative regulator of T-cell activation.
Subunit:
Homodimer. Interacts with MARCH8. Interacts with human herpesvirus 8 MIR2 protein (Probable). Interacts with adenovirus subgroup B fiber proteins and acts as a receptor for these viruses.
Subcellular Location:
Cell membrane; Single-pass type I membrane protein.
Tissue Specificity:
Expressed by activated B-lymphocytes and monocytes.
Post-translational modifications:
Polyubiquitinated; which is promoted by MARCH8 and results in endocytosis and lysosomal degradation.
Similarity:
Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
Contains 1 Ig-like SLVtype (immunoglobulin-like) domain.
