Qa-1b&B2M&Qdm (AMAPRTLLL) Monomer, His & Avi, Mouse

Qa-1b&B2M&Qdm (AMAPRTLLL) Monomer, His & Avi, Mouse

Qa-1b binds a peptide (AMAPRTLLL), referred to as Qdm (for Qa-1 determinant modifier), derived from the signal sequence of murine class Ia molecules. This peptide binds with high affinity and accounts for almost all of the peptides associated with this molecule. Human histocompatibility leukocyte antigen (HLA)-E, a homologue of Qa-1b, binds similar peptides derived from human class Ia molecules and interacts with CD94/NKG2 receptors on natural killer cells.
