Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation, IF-IC=Immunofluorescence (Immunocytochemistry)
Specificity / Sensitivity
TIAR (D26E4) Rabbit mAb recognizes endogenous levels of total TIAR protein. This antibody also weakly recognizes recombinant TIA1 protein.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human TIAR protein.
Western blot analysis of extracts from HeLa and Hep G2 cells using TIAR (D26E4) Rabbit mAb.
TIAR is a member of the RNA-recognition motif (RRM) family of RNA-binding proteins (1,2). It functions as a translational repressor under conditions of cellular damage (3,4). In response to cellular stress, TIAR associates with eIF1, eIF3, and the 40S ribosomal subunit and forms noncanonical preinitiation complexes that are translationally inactive (3,4). TIAR then aggregates with its family member TIA1 and facilitates the accumulation of the translationally inactive preinitiation complexes into discrete cytoplasmic foci called stress granules. The two major isoforms of TIAR are the products of alternative mRNA splicing (5,6).
