NCIt definition : Nucleolysin TIA-1 isoform p40 (386 aa, 43 kDa) is encoded by the human TIA1 gene.
This protein is involved in RNA binding, alternative splicing, translational regulation
and nucleolysis.;
NCIt note : Nucleolysin TIA-1 isoform p40 binds to to AU-rich elements (AREs) located in the 3'
untranslated regions (3' UTRs) of mRNA. (UniProt); The major granule-associated species is a 15 kDa protein that is expressed in cytolytic
lymphocytes (CTLs) and natural killer cells. It is thought to be derived from the
carboxyl terminus of the 40 kDa product by proteolytic processing because no alternative
promoter sites have been found. (EntrezGene);
