| 产品简介 (Background) |
Beyotime's Recombinant Human TIM4 (His-Tag&Avi-Tag) was expressed in HEK293 and purified, which contain the extracellular domain (25-314aa) of human TIM4 with His-Tag and Avi-Tag fusion at the C-terminus. TIMs are type I transmembrane proteins, with the N terminus containing the variable Ig-like (IgV) domain extending from the plasma membrane and the C-terminal tail largely mediating intracellular signaling oriented toward the cytosol. The Tim gene family consists of eight members (Tim-1-8) on mouse chromosome 11B1.1 and three members (Tim-1, Tim-3, and Tim-4) on human chromosome 5q33.2. TIM1, TIM2, and TIM3 were all found to be expressed by T cells and involved in the regulation of Th cells. TIM4 is different from other TIM molecules in that it is expressed exclusively on antigen-presenting cells (APCs), particularly on mature myeloid-derived DCs and macrophages but not by lymphocytes. Mature human TIM4 consists of a 290aa extracellular domain (ECD), a 21aa transmembrane segment and a 43aa cytoplasmic tail. TIM4 is involved in immune regulation such as to initiate skewed Th2 polarization and to mediate phagocytosis of apoptotic cells. TIM4 also binds specifically to TIM1 which is also the cellular receptor for hepatitis A virus and has been implicated in the development of asthma. TIM4 is also found in tumor tissue such as histiocytic and dendritic cell neoplasms, which consistently express TIM4. It has been suggested that these molecules can be new markers of neoplasms derived from histiocytic and dendritic cells. TIM4 contains IgV domain with integrin-binding site as well as a unique metal-ion-dependent ligand binding site for phosphatidylserine (PS). Binding of TIM4 to PS displays the highest affinity and depends on Ca2+. This feature allows to efficiently capture SEVs（Small extracellular vesicles）using TIM4-beads and then elute intact SEVs from the TIM4-beads [1-2]. |
| 产品用途 (Applications) |
Ligand for HAVCR1/TIMD1. Phosphatidylserine receptor that enhances the engulfment of apoptotic cells. Involved in regulating T-cell proliferation and lymphotoxin signaling. Recombinant Human TIM4 (His-Tag&Avi-Tag) can be used to detect or isolate apoptotic cells or exosomes. |
