Background

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 (1 - 3). The mouse TIM-4 cDNA encodes a 343 amino acid (aa) precursor that includes a 22 aa signal sequence, a 257 aa extracellular domain (ECD), a 21 aa transmembrane segment, and a 43 aa cytoplasmic tail (4). 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. The mucin domain in TIM-4 is larger than in TIM-1, -2, or -3. Within the ECD, mouse TIM-4 shares 27 - 33% aa sequence identity with mouse TIM-1, -2, and -3. The ECD of mouse TIM-4 shares 45% aa sequence identity with that of human and rat TIM-4. TIM-4 is expressed by macrophages and mature dendritic cells but not by lymphocytes (4, 5). TIM-4 binds specifically to TIM-1 which is also the cellular receptor for hepatitis A virus and has been implicated in the development of asthma (5 - 7). Among hematopoietic cells, TIM-1 is expressed on activated B and T cells, preferentially in the Th2 subset of CD4⁺ T cells (5, 8). The interaction ofTIM-4 with TIM-1 induces co-stimulatory and hyperproliferative signals in T cells (5).
