| T cell receptor |
- TCR is a heterodimer consisting of alpha and beta chain
- A variable region the hypervariable region determines the specificity
- A constant region
- A transmembrane region for anchorage
- And a short cytoplasmic region that interacts with cytoskeletal structures
- Each T cell bears a TCR of single specificity
