Description

General description

Antigen-presenting glycoprotein CD1d (UniProt P15813; also known as CD1d, R3G1) is encoded by the CD1D gene (Gene ID 912) in human. CD1d is an MHC-like glycoprotein expressed on epithelial cells and can signal innate immune responses by presenting lipid antigen to natural killer (NK) and NK T (NKT) cells. Similar to MHC class I heavy chain (HC), CD1d HC is glycosylated and assembled with β2m in ER. Unlike MHC class I HC, misfoled CD1d and CD1d not properly assembled with β2m are not destroyed by ER quality control mechanisms. CD1d plays a role in both innate and adaptive immunity to various bacteria, viruses, fungi, and parasites. Activation of CD1d-restricted invariant NKT cells enhances host resistance to these microbes via direct killing of CD1d-expressing (infected) cells or by promoting interferon gamma release from conventional NK cells and by modulating adaptive immune cells via alteration of Th1/Th2 polarization. Chlamydia trachomatis is shown to prevent CD1d-mediated innate immune destruction of the infected urethral epithelial cells by targeting CD1d for proteolytic degradation. Specifically, the chlamydial proteasome-like activity factor (CPAF) interacts with the CD1d HC, and CPAF-associated CD1d HC is then ubiquitinated for eventual degradation.

This Anti-CD1d Antibody, clone D5 is validated for use in Western Blotting, Immunoprecipitation for the detection of CD1d.

Western Blotting Analysis: A representative lot detected time-dependent CD1d degradation in CD1d immunoprecipitate from human penile urethral epithelial (PURL) cells following C. trachomatis infection (Kawana, K., et al. (2007). J Biol Chem. 282(10):7368-7375).
Western Blotting Analysis: A representative lot detected exogenously expressed CD1d in CD1d-transfected C1R human lymphoblastoid cells (Kim, H.S., et al. (1999). J Biol Chem. 274(14):9289-9295).
Immunoprecipitation Analysis: A representative lot immunoprecipitated intact as well as degraded CD1d from human penile urethral epithelial (PURL) cells following C. trachomatis (Kawana, K., et al. (2007). J Biol Chem. 282(10):7368-7375).
Immunoprecipitation Analysis: A representative lot immunoprecipitated exogenously expressed CD1d independent of glycosylation states from lysates of CD1d-transfected FO-1 human melanoma cells (Kim, H.S., et al. (1999). J Biol Chem. 274(14):9289-9295).

Quality

Evaluated by Western Blotting in THP-1 cell lysate.

Western Blotting Analysis: 4.0 µg/mL of this antibody detected CD1d in 10 µg of THP-1 cell lysate.
Note: Longer exposure time is needed when using total lysates for Western blotting applications. Membrane preparation or immunoprecipitation can be employed to enrich membrane target proteins prior to Western blotting.
