StorageThe shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20˚C,-80˚C. The shelf life of lyophilized form is 12 months at -20˚C,-80˚C.
Notes:Repeated freezing and thawing is not recommended. Store working aliquots at 4˚C for up to one week.
Tag InfoN-terminal 6xHis-SUMO-tagged
Application Details
Binds the poly(A) tail of mRNA, including that of its own transcript. May be involved in Cytoplasmic domain regulatory processes of mRNA metabolism such as pre-mRNA splicing. Its function in translational initiation regulation can either be enhanced by PAIP1 or repressed by PAIP2. Can probably bind to Cytoplasmic domain RNA sequences other than poly(A) in vivo. Involved in translationally coupled mRNA turnover. Implicated with other RNA-binding proteins in the Cytoplasmic domain deadenylation,translational and decay interplay of the FOS mRNA mediated by the major coding-region determinant of instability (mCRD) domain. Involved in regulation of nonsense-mediated decay (NMD) of mRNAs containing prature stop codons; for the recognition of prature termination codons (PTC) and initiation of NMD a competitive interaction between UPF1 and PABPC1 with the ribosome-bound release factors is proposed.
