Recombinant Human TIMD4 protein, Fc-tagged

Cat.No.: TIMD4-244H
Product Overview: Recombinant Human TIMD4(Glu25-Gln314) fused Fc region of Human IgG1 was expressed in HEK293.
Description: TIM-4 (T cell; immunoglobulin; mucin-4), also known as SMUCKLER, is a 60 kDa member of the TIM family of immune regulating proteins. TIMs are type I transmembrane proteins with one Ig-like V domain and one Ser/Thr-rich mucin domain. Mature human TIM-4 consists of a 290 aa extracellular domain (ECD), a 21 aa transmembrane segment, and a 43 aa cytoplasmic tail. Structurally, TIM-4 is distinguished from other TIMs by the presence of an RGD motif in its Ig domain and the lack of a site for tyrosine phosphorylation in its cytoplasmic tail. Within the ECD human TIM-4 shares 45% aa sequence identity with mouse and rat TIM-4. TIM-4 is expressed by macrophages and mature dendritic cells but not by lymphocytes. It binds specifically to TIM-1 which is also the cellular receptor for hepatitis A virus and has been implicated in the development of asthma. Among hematopoietic cells, TIM-1 is expressed on activated B and T cells, preferentially in the Th2 subset of CD4+ T cells. The interaction of TIM-4 with TIM-1 induces co-stimulatory and hyperproliferative signals in T cells. TIM-4 also binds to phosphatidylserine (PS) on the surface of apoptotic cells. It enhances the clearance of apoptotic cells including T cells in the contraction phase of immune responses, apoptotic macrophages that accumulate in atherosclerosis, and dying neurons in the brain. TIM-4 is upregulated on some tumor cells and tumor-associated myeloid cells where it binds Integrin alpha V beta 3, contributes to tumor progression, and inhibits tumor-specific cellular immunity.
