ULBP2 (UL16 binding protein 2) is a ligand of natural killer group 2, member D (NKG2D), an immune system-activating receptor on NK cells and T-cells. ULBP2 is a GPI-anchored glycoprotein that belongs to the MHC-I family of Immunoglobulin superfamily (IgSF).  Binding of the ligand including ULBP1, ULBP2 and ULBP3, to NKG2D leads to activation of several signal transduction pathways, including those of JAK2, STAT5, ERK and PI3K kinase/Akt, resulting in the production of cytokines and chemokines. ULBP2 does not bind to beta2-microglobulin. In cytomegalovirus-infected cells, this ligand binds the UL16 glycoprotein. The interaction with UL16 blocked the interaction with the KLRK1/NKG2D receptor, providing a mechanism by which CMV infected cells might escape the immune system. UL16 also causes ULBP2 to be retained in the ER and cis-Golgi apparatus so that it does not reach the cell surface.

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
