| PF16680 | T-cell surface glycoprotein CD3 delta chain (Ig_4) | T-cell surface glycoprotein CD3 delta chain | This is an immunoglobulin-like domain. It is found on the T-cell surface glycoprotein CD3 delta chain. CD3delta and CD3epsilon complex together as part of the T-cell receptor complex [1]. | Domain | |
| PF16681 | Ig-like domain on T-cell surface glycoprotein CD3 epsilon chain (Ig_5) | Ig-like domain on T-cell surface glycoprotein CD3 epsilon chain | Ig_5 is an immunoglobulin domain found on T-cell surface glycoprotein CD3 epsilon chain. It forms a first-order complex with T-cell surface glycoprotein CD3 delta chain as part of the T-cell receptor complex [1]. | Domain | |
