What (who) is 4F2 cell-surface antigen heavy chain - definition


4F2 cell-surface antigen heavy chain         
4F2 cell-surface antigen heavy chain is a protein that in humans is encoded by the SLC3A2 (solute carrier family 3 member 2) gene.
Heavy-chain antibody         
  • A heavy-chain shark antibody (left) and a heavy-chain camelid antibody (middle) in comparison to a common antibody (right). Heavy chains are shown in a darker shade, light chains in a lighter shade.
ANTIBODY COMPOSED OF HEAVY CHAINS ONLY
Heavy-chain immunoglobulin; Heavy chain antibodies; Immunoglobulin new antigen receptor; IgNAR; Heavy chain antibody; Heavy-chain antibodies
A heavy-chain antibody is an antibody which consists only of two heavy chains and lacks the two light chains usually found in antibodies.
T-cell receptor         
  • Antigen presentation stimulates T cells to become either "cytotoxic" CD8+ cells or "helper" CD4+ cells.
MOLECULE FOUND ON THE SURFACE OF SOME IMMUNE CELLS
Alpha-beta T-cell antigen receptor; Genes, t-cell receptor; T-cell receptors; Receptors, antigen, t-cell; T-cell antigen receptors; TCRδ1; TCRd1; T cell receptor
The T-cell receptor (TCR) is a protein complex found on the surface of T cells, or T lymphocytes, that is responsible for recognizing fragments of antigen as peptides bound to major histocompatibility complex (MHC) molecules. The binding between TCR and antigen peptides is of relatively low affinity and is degenerate: that is, many TCRs recognize the same antigen peptide and many antigen peptides are recognized by the same TCR.
