Application Notes:

Additional reported applications (for relevant formats) include: immunoprecipitation1 and blocking2, 3 of CHO cell or Con A-activated lymphoblast killing by NK cells.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.25 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Description:

Ly49D is a type II transmembrane protein belonging to the Ly49 family of NK-cell receptors in the C-type lectin superfamily.  Ly49D is expressed on subsets of natural killer (NK) cells in C57BL/6, C3H/He and SJL mouse strains, but not Balb/c, DBA/2, AKR and CBA/J.  The receptors form homodimers that bind to MHC class I alloantigens.  Unlike inhibitory Ly49 family members, Ly49D lacks a cytoplasmic immunoreceptor tyrosine-based inhibitory motif (ITIM) but contains a cytoplasmic immunoreceptor tyrosine-based activation motif.  The activating receptor Ly49D delivers stimulatory signals for target cell lysis upon interacting with H2-Dd, Dr and Dsp2, but not with H2b or H2k class I antigens.  Cross-linking of Ly49D activates intracellular kinase activity and calcium mobilization in NK cells.  In 129/J mice, 4E5 antibody cross-reacts with Ly49O, LY49R and Ly49V.

Other Names: Ly-49D
Structure: A type II transmembrane protein belonging to the Ly49 family of NK-cell receptors in the C-type lectin superfamily.
Distribution: Subsets of natural killer (NK) cells in C57BL/6, C3H/He and SJL, but not Balb/c, DBA/2, AKR and CBA/J.
Function: Plays an important role in activating natural killer (NK) cell cytolytic activity.
Ligand Receptor: MHC class I alloantigens
