Hepatitis A virus cellular receptor 1 is a human gene encoded by the symbol, HAVCR1. It may also be known as: HAVcr-1; Kidney injury molecule 1; KIM-1; T-cell immunoglobulin and mucin domain-containing protein 1; TIMD-1; T-cell immunoglobulin mucin receptor 1; TIM-1; T-cell membrane protein 1; T-cell immunoglobulin mucin family member 1; HAVCR; KIM1; TIMD1. The encoded protein has an amino acid length of 359 and a mass of 38.7 kDa. Hepatitis A virus cellular receptor 1 is a member of the Immunoglobulin superfamily, TIM family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
