Structure of the Human KIM-1 protein. Schematic representation of KIM-1, showing the signal peptide, IgV, mucin, transmembrane, and cytoplasmic domains. The triangles are the predicted location of N-linked glycosylation sites. KIM-1, kidney injury molecule-1; MLIBS, metal ion-dependent ligand binding site; T/S/P, threonine/serine/proline; TM, transmembrane.
