Human CD96/TACTILE Protein, ECD (Extracellular Domain), Fc-fusion, Biotinylated, Recombinant

Description

CD96, also known as Tactile (T cell-activated increased late expression), is a single pass type I transmembrane protein of the immunoglobulin superfamily (IgSF).  The extracellular domain (ECD) of CD96 contains 2 V-type and 1 C-type Ig-like domains, which are highly glycosylated.  An 80-kDa soluble form of CD96 is elevated in human serum during chronic hepatitis B. CD96 is expressed on activated T, NK and a subpopulation of B cells as well as on acute myeloid leukemia and  myelodysplastic stem cells. CD96 is allocated to the repertoire of human NK receptors. NK cells recognize poliovirus receptor (PVR) or CD155, a nectins and nectin-like protein family member serve to mediate cell-cell adhesion and cell migration. CD96 may be involved in adhesive interactions of activated T and NK cells during the late phase of the immune response.  CD96 promotes NK cell adhesion to target cells expressing PVR, stimulates cytotoxicity of activated NK cells. The most N-terminal Ig-like domain of CD96 binds to PVR.  On NK cells, co-stimulatory molecules CD96 and DNAM-1 (CD226) are thought to have paired activity with inhibitory TIGIT, all of which bind CD155 and various members of nectin family.   CD96 may function at a time after T and NK cells have penetrated the endothelium using integrins and selectins, when they are actively engaging diseased cells and moving within areas of inflammation.  CD96 mutations may cause a form of the C syndrome, a set of developmental anomalies in cranial bone, skin and viscera.  

 

 

Gene Symbol: CD96; TACTILE

 

NCBI Gene ID: 10225
