Nuclear inhibitor of protein phosphatase 1 (PPP1R8), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 1-209aa. Protein Length: Full Length of Isoform 2. Tag Info: N-terminal GST-tagged. Target Protein Sequence: MGGEDDELKG LLGLPEEETE LDNLTEFNTA HNKRISTLTI EEGNLDIQRP KRKRKNSRVT FSEDDEIINP EDVDPSVGRF RNMVQTAVVP VKKKRVEGPG SLGLEESGSR RMQNFAFSGG LYGGLPPTHS EAGSQPHGIH GTALIGGLPM PYPNLAPDVD LTPVVPSAVN MNPAPNPAVY NPEAVNEPKK KKYAKEAWPG KKPTPSLLIL ENGTHMASSD ACHECKSMIA AAG. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The 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. Relevance: Inhibitor subunit of the major nuclear protein phosphatase-1 (PP-1). It has RNA-binding activity but does not cleave RNA and may target PP-1 to RNA-associated substrates. May also be involved in pre-mRNA splicing. Binds DNA and might act as a transcriptional repressor. Seems to be required for cell proliferation. Isoform Gamma is a site-specific single-strand endoribonuclease that cleaves single strand RNA 3' to purines and pyrimidines in A+U-rich regions. It generates 5'-phosphate termini at the site of cleavage. This isoform does not inhibit PP-1. May be implicated in mRNA splicing. Reference: "ard-1: a human gene that reverses the effects of temperature-sensitive and deletion mutations in the Escherichia coli rne gene and encodes an activity producing RNase E-like cleavages."
