NKG2-A/NKG2-B Type II Integral Membrane Recombinant Protein | NKG2-A recombinant protein
Recombinant Human NKG2-A/NKG2-B Type II Integral Membrane Protein
After reconstitution, the protein solution is stable at -20 degree C for 3 months, at 2-8 degree C for up to 1 week.
Background: NKG2-A/NKG2-B Type II Integral Membrane Protein contains 1 C-type lectin domain and belongs to the killercell lectin-like receptor family. The killer cell lectin-like receptor family is a group of transmembrane proteinspreferentially expressed in NK cells. Members of this proteins is characterized by the type II membraneorientation and the presence of a C-type lectin domain. NKG2 is expressed only in NK-cells, but not in T-cells orB-cells. It has been shown that NKG2 represents a family of related cDNA clones, designated NKG2A, NKG2B,NKG2C, and NKG2D, which encode type 2 integral membrane proteins (extracellular C-terminus) containing aC-type lectin domain. NKG2 plays a role as a receptor for the recognition of MHC class I HLA-E molecules by NKcells and some cytotoxic T-cells. NKG2A and NKG2B have been given the designation CD159a in thenomenclature of CD antigens.
NCBI and Uniprot Product Information
NCBI Description
Natural killer (NK) cells are lymphocytes that can mediate lysis of certain tumor cells and virus-infected cells without previous activation. They can also regulate specific humoral and cell-mediated immunity. The protein encoded by this gene belongs to the killer cell lectin-like receptor family, also called NKG2 family, which is a group of transmembrane proteins preferentially expressed in NK cells. This family of proteins is characterized by the type II membrane orientation and the presence of a C-type lectin domain. This protein forms a complex with another family member, KLRD1/CD94, and has been implicated in the recognition of the MHC class I HLA-E molecules in NK cells. The genes of NKG2 family members form a killer cell lectin-like receptor gene cluster on chromosome 12. Multiple alternatively spliced transcript variants encoding distinct isoforms have been observed. [provided by RefSeq, Jan 2015]
