Anti-TIA-1

0.5mg/ml if reconstituted with 0.2ml sterile DI water. TIA-1 (T-Cell Intracellular Antigen-1), also called WDM, is an RNA-binding protein involved in splicing regulation and translational repression. It is a member of a RNA-binding protein family and possesses nucleolytic activity against cytotoxic lymphocyte(CTL) target cells. By in situ hybridization, the gene is mapped to chromosome 2p13.3. It has been suggested that this protein may be involved in the induction of apoptosis as it preferentially recognizes poly(A) homopolymers and induces DNA fragmentation in CTL targets. The major granule-associated species is a 15-kDa protein that is though to be derived from the carboxyl terminus of the 40-kDa product by proteolytic processing. Protein function: Involved in alternative pre-RNA splicing and regulation of mRNA translation by binding to AU-rich elements (AREs) located in mRNA 3' untranslated regions (3' UTRs). Possesses nucleolytic activity against cytotoxic lymphocyte target cells. May be involved in apoptosis. [The UniProt Consortium]
