简介
The LILRB1/CD85j/ILT2 protein is a receptor for class I MHC antigens and recognizes multiple HLA alleles and H301/UL18 (human cytomegalovirus MHC homolog). Ligand binding induces inhibitory signals that downregulate immune responses. LILRB1/CD85j/ILT2 Protein, Human (346a.a, HEK293, His) is the recombinant human-derived LILRB1/CD85j/ILT2 protein, expressed by HEK293 , with C-His labeled tag.

Protein Description
LILRB1, also known as CD85j or ILT2 (Immunoglobulin-like transcript 2), is a crucial immune checkpoint receptor belonging to the LILR (Leukocyte Immunoglobulin-like Receptor) family. It is primarily expressed on various immune cells, including monocytes, macrophages, and dendritic cells, where it plays a fundamental role in regulating immune responses. The receptor recognizes major histocompatibility complex (MHC) class I molecules, which allows it to modulate the activation and inhibition of immune cell functions. Due to its immunoregulatory capabilities, LILRB1 is considered a significant player in maintaining immune tolerance and preventing excessive inflammation, making it a potential target for therapeutic interventions in autoimmune diseases and cancer. The development of recombinant LILRB1/CD85j/ILT2 proteins enables researchers to explore its biological functions and interactions in detail, facilitating the understanding of its role in immune modulation. By studying these recombinant proteins, scientists aim to decipher the molecular mechanisms underlying LILRB1 signaling and its impact on immune cell behavior, paving the way for innovative treatments that leverage this checkpoint receptor in immunotherapy and transplant medicine. Overall, LILRB1’s unique properties and its emerging significance in immune regulation underscore the importance of continued research into its potential applications.
