Recombinant Human KLRG1/CLEC15A Protein, N-His

Introduction to Recombinant Human KLRG1/CLEC15A Protein

Recombinant Human KLRG1/CLEC15A Protein is a type I transmembrane glycoprotein that belongs to the C-type lectin family. It is also known as killer cell lectin-like receptor G1 (KLRG1) or C-type lectin domain family 15 member A (CLEC15A). This protein is encoded by the KLRG1 gene and is primarily expressed on natural killer (NK) cells, T cells, and subsets of B cells and myeloid cells.

Structure of Recombinant Human KLRG1/CLEC15A Protein

The recombinant form of KLRG1/CLEC15A protein is produced through genetic engineering techniques, where the gene encoding for the protein is inserted into a suitable expression system. The resulting protein is a homodimer with a molecular weight of approximately 30 kDa. It contains an extracellular C-type lectin-like domain, a transmembrane domain, and a cytoplasmic tail. The extracellular domain is responsible for binding to its ligand, while the cytoplasmic tail contains signaling motifs that regulate the activity of the protein.

Activity of Recombinant Human KLRG1/CLEC15A Protein

KLRG1/CLEC15A protein is a type II transmembrane receptor that plays a crucial role in the regulation of immune responses. It acts as an inhibitory receptor and is involved in the modulation of NK cell and T cell cytotoxicity. The binding of KLRG1/CLEC15A to its ligand results in the recruitment of phosphatases, which inhibit the signaling pathways involved in cell activation. This ultimately leads to the suppression of immune responses, which is important for maintaining immune homeostasis and preventing autoimmunity.

Interaction with Ligands

The ligand for KLRG1/CLEC15A protein is not yet fully identified, but it is believed to be a carbohydrate or glycoprotein present on the surface of target cells. Studies have shown that KLRG1/CLEC15A can interact with several ligands, including E-cadherin, Galectin-3, and MHC class I molecules. The binding of KLRG1/CLEC15A to its ligand results in the inhibition of NK cell and T cell cytotoxicity, as well as the downregulation of cytokine production.

Applications of Recombinant Human KLRG1/CLEC15A Protein

Recombinant Human KLRG1/CLEC15A Protein has various applications in scientific research and potential therapeutic uses. Some of the key applications include:

Immune System Studies
