OCILRP2/CLEC2i Antibody

Membrane co-localization of OCILRP2 and DAP12 under anti-CD3/CD28 mAb treatment in EL4 T cells.EL4 T cells pre-transfected with pEGFP-siOCILRP2 or pre-coated with the OCILRP2 Ab were cultured overnight in the presence or absence of an anti-CD3/CD28 mAb and then stained for OCILRP2 (green) and nuclear stained with DAPI (blue) and DAP12 (red) to study OCILRP2 and DAP12 protein expression and localization. Unstimulated EL4 T cells exhibited OCILRP2 protein expression in the cytoplasm (upper panels). In contrast, CD3/CD28-activated EL4 T cells showed intracellular and membrane OCILRP2. OCILRP2/DAP12 co-localization appears in yellow. Each picture is representative of the vast majority of the observed cells on the slides.

Background

OCILRP2, also known as CLRG (C-type lectin related g) and CLEC2i (C-type lectin domain family 2, member i), is a type II transmembrane protein whose gene has been mapped to the natural killer gene complex (NKC) on mouse chromosome 6. By alternative splicing, multiple isoforms exist. OCIL RP2 is expressed on osteoclasts, chondrocytes and lymphoid cell types. It is a ligand for NKrp1f (KLRB1f), another NK receptor on the NKC. OCILRP2 inhibits osteoclast formation and can affect NK cell functions. The extracellular domain of mouse OCILRP2 shares 79% and 74% amino acid sequence identity with that of mouse OCILRP1 and OCIL, respectively. A human OCILRP2 ortholog has not been identified.
