TIA1 is a 3'UTR mRNA binding protein that can bind the 5'TOP sequence of 5'TOP mRNAs. It is associated with programmed cell death (apoptosis) and regulates alternative splicing of the gene encoding the Fas receptor, an apoptosis-promoting protein.[1] Under stress conditions, TIA1 localizes to cellular RNA-protein conglomerations called stress granules.[2]
Mutations in the TIA1 gene have been associated with amyotrophic lateral sclerosis, frontotemporal dementia, and Welander distal myopathy.[3][4][5]
