Gene name
KIR2DL1

简介
KIR2DL1, found on NK cells, serves as a receptor for specific HLA-C alleles, inhibiting NK cell activity to prevent cell lysis. This regulatory function involves interactions with ARRB2 and, additionally, engages PTPN6 and PTPN11. The interaction's enhancement by ARRB2 underscores KIR2DL1's role in complex signaling networks that modulate NK cell function. KIR2DL1 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived KIR2DL1 protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

Protein Description
KIR2DL1 (Killer Immunoglobulin-like Receptor 2DL1) is a receptor expressed on natural killer (NK) cells and a subset of T cells, playing a critical role in the immune response against tumor cells and virus-infected cells. It interacts specifically with HLA-C molecules, modulating NK cell activity and influencing immune tolerance and response. The understanding of KIR2DL1 and its signaling mechanisms has profound implications in cancer immunotherapy and transplantation, as variations in its expression and function can affect an individual's susceptibility to infections and cancer development. The study of KIR2DL1 recombinant proteins is essential for elucidating the structure-function relationship of this receptor, enabling the development of targeted therapies. Furthermore, recombinant KIR2DL1 proteins are valuable tools in elucidating the molecular interactions between NK cells and their ligands, advancing our understanding of immune regulation. Investigating these proteins can lead to insights into how KIR2DL1 modulates NK cell activation and inhibition, potentially guiding the design of KIR2DL1-targeted strategies in clinical settings for enhancing anti-tumor immunity or tolerating transplanted tissues. As research progresses, a deeper characterization of KIR2DL1 recombinant proteins will contribute to the overall understanding of NK cell biology and pave the way for innovative therapeutic approaches in the context of immunology and oncology.
