TIM-1/KIM-1/HAVCR Proteins and Enzymes

TIM-1 (T cell immunoglobulin and mucin domain 1), also known as KIM-1 and HAVcr1, is expressed on many immune cell types and epithelial cells. It binds to phosphatidylserine (PS), LMIR5/CD300b, TIM-1 (homophilic), TIM-4, IgA, and the glycoproteins of a number of enveloped viruses. Its interaction with PS enables TIM-1 to mediate the phagocytosis and clearance of apoptotic cells. TIM-1 signaling costimulates T cell activation and enhances Th2 cytokine production. TIM-1 serves as a cellular entry ...
