TIA1 encodes the human gene, TIA1 cytotoxic granule-associated RNA binding protein. It may also be known as: Nucleolysin TIA-1 isoform p40; T-cell-restricted intracellular antigen-1; TIA-1; p40-TIA-1; RNA-binding protein TIA-1. The encoded protein has an amino acid length of 386 and a mass of 43.0 kDa. Other isoforms may exist. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
