TIA1, also named as p40-TIA-1, is 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). It possesses nucleolytic activity against cytotoxic lymphocyte target cells. TIA1 may be involved in apoptosis. Two isoforms of this protein exist - 41kDa and 42kDa. one of these was a missense variant (P362L) in TIA1. Similar to the ALS-related disease proteins TDP-43, hnRNPA1, and FUS, TIA1 is an RNA-binding protein containing a prionlike LCD and assembles into membrane-less organelles, including SGs. Postmortem neuropathology of five TIA1mutations carriers showed a consistent pathological signature with numerous round, hyaline, TAR DNA-binding protein 43 (TDP-43)-positive inclusions.TIA1mutations significantly increased the propensity of TIA1 protein to undergo phase transition. In live cells,TIA1mutations delayed stress granule (SG) disassembly and promoted the accumulation of non-dynamic SGs that harbored TDP-43. Moreover, TDP-43 in SGs became less mobile and insoluble.

haibo (Verified Customer) (09-28-2020)
Western blotting was good. But can not see clear granule signal even after treatment by IF. The cells used were fibroblasts.
Manohar (Verified Customer) (09-23-2020)
Used 1% Milk for blocking
Joshua (Verified Customer) (12-28-2019)
PANC1 cells fixed in 4% paraformaldehyde and stained overnight at 4C. Bright staining, mix of nuclear and stress granule localization as expected.
Joshua (Verified Customer) (12-12-2018)
We found acetone fixation (20 min in 100% acetone at -20C) worked better than paraformaldehyde.
