Activity summary

KLRF1 also known as CD314 or NKp80 is a receptor protein found primarily on natural killer (NK) cells with a significant mass of about 30 kDa. Researchers have identified its expression mainly in tissues rich in NK cells such as the spleen and peripheral blood. This receptor structurally belongs to the C-type lectin-like domain family and plays an important role in the immune response by binding to the CLEC2B ligand on target cells facilitating NK cell activation and cytotoxicity.

Biological function summary

In immune surveillance and homeostasis KLRF1 acts as an important activating receptor on natural killer cells. It does not form a complex but works independently to control cellular immune responses by recognizing stress-induced ligands on target cells. Upon interaction with its ligand KLRF1 triggers a cascade of intracellular signals that promote cytotoxic activity and cytokine secretion contributing to the elimination of virally infected or transformed cells.

Pathways

In the context of innate immune response signaling KLRF1 interacts with pathways involving NK cell-mediated cytotoxicity. KLRF1 engagement stimulates pathways similar to those activated by other receptors in the natural killer cell repertoire such as KLRK1 (NKG2D). These interactions play roles in maintaining balance within the immune system by modulating NK cell activity and ensuring efficient target cell elimination.

Associated diseases and disorders

KLRF1 has implications in immune system-related conditions such as cancers and viral infections. Altered expression or function of KLRF1 may contribute to the escape of tumor cells from immune surveillance or decreased viral clearance. Associations with proteins like KLRD1 (CD94) in certain hematological malignancies suggest a role for KLRF1 in disease pathogenesis where NK cell dysfunction is present underlining its significance in developing therapeutic interventions.
