Study Notes

Immunoglobulins and Receptors

  • Two possible proteins for the light chain in an immunoglobulin: κ (kappa) and λ (lambda)

Immunoglobulin Structure

  • IgM has 5 antigen binding sites in its normal arrangement

T Cell Receptors (TCRs)

  • Correct structure: αβ or γδ (alpha-beta or gamma-delta)

B Cell Receptors (BCRs)

  • Signals are mediated by Igα and Igβ proteins

Antigen Recognition

  • B cell receptors (BCRs) mainly recognize protein antigens

Test your knowledge of immunoglobulin proteins and T cell receptors with this quiz. Explore topics such as light chain proteins, antigen binding sites, T cell receptor structure, and antigens recognized by TCRs and BCRs.
