T lymphocyte immunoglobulin mucin-domain containing-protein-3 (TIM-3)

Target
TIM-3
Molecular classification
Type I transmembrane protein, Immunoregulatory protein, Receptor
01

Overview

TIM-3 is a type I transmembrane protein and a member of the TIM family of immunoregulatory proteins. It is expressed on various immune cells, including T cells, NK cells, dendritic cells, and macrophages. TIM-3 functions as an immune checkpoint receptor with both inhibitory and activating roles, depending on the cellular context and ligand engagement. It is implicated in autoimmunity, cancer, and chronic infections, and is being explored as a therapeutic target for cancer immunotherapy.
