Detection of TIM-1/KIM-1/HAVCR in HEK293 Human Cell Line Transfected with Human TIM-1/KIM-1/HAVCR and eGFP by Flow Cytometry HEK293 human embryonic kidney cell line transfected with (A) human TIM-1/KIM-1/HAVCR or (B) irrelevant protein, and eGFP was stained with Rabbit Anti-Human TIM-1/KIM-1/HAVCR Monoclonal Antibody (Catalog # MAB17504) followed by Allophycocyanin-conjugated Anti-Rabbit IgG Secondary Antibody (F0111). Quadrant markers were set based on control antibody staining (MAB1050). Staining was performed using our Staining Membrane-associated Proteins protocol.

TIM‑1/KIM‑1/HAVCR in Human Kidney Tissue. TIM‑1/KIM‑1/HAVCR was detected in immersion fixed paraffin-embedded sections of human kidney tissue using Rabbit Anti-Human TIM‑1/KIM‑1/HAVCR Monoclonal Antibody (Catalog # MAB17504) at 3 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Rabbit IgG VisUCyte™ HRP Polymer Antibody (VC003). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cell membrane in convoluted tubules. Staining was performed using our protocol for IHC Staining with VisUCyte HRP Polymer Detection Reagents.

Background: TIM-1/KIM-1/HAVCR

TIM-1 (T cell-Immunoglobulin-Mucin; also KIM-1 and HAVcr-1) is a 100 kDa, type I transmembrane glycoprotein member of the TIM family of immunoglobulin superfamily molecules (1-3). This gene family is involved in the regulation of Th1 and Th2-cell-mediated immunity. Human TIM-1 is synthesized as a 359 amino acid (aa) precursor that contains a 20 aa signal sequence, a 270 aa extracellular domain (ECD), a 21 aa transmembrane segment and a 48 aa cytoplasmic domain (4-6). The ECD contains one V-type Ig-like domain and a mucin region characterized by multiple PTTTTL motifs. The mucin region undergoes extensive O-linked glycosylation. The TIM-1 gene is highly polymorphic and undergoes alternate splicing (1). For instance, the presence of a six aa sequence (MTTTVP) at position # 137 of the mature molecule is associated with protection from atopy in people with a history of hepatitis A (7, 8). There are two cytoplasmic alternate splice forms of TIM-1. One is a long (359 aa) kidney form termed TIM-1b, and one is a short (334 aa) liver form termed TIM-1a. Both are identical through the first 323 aa of their precursors. TIM-1b contains a tyrosine phosphorylation motif that is not present in 1a (6). TIM-1 is also known to circulate as a soluble form. Constitutive cleavage by an undefined MMP (possibly ADAM33) releases an 85-90 kDa soluble molecule (6). The ECD of human TIM-1 is 50% and 43% aa identical to mouse and canine TIM-1 ECD, respectively. The only two reported ligands for TIM-1 are TIM-4 and the hepatitis A virus (4, 9). However, others are believed to exist, and based on the ligand for TIM-3, one may well be an S-type lectin (10). TIM-1 ligation induces T cell proliferation and promotes cytokine production (1, 10).
