Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IHC-P=Immunohistochemistry (Paraffin)
Specificity / Sensitivity
Phospho-PP1α (Thr320) Antibody detects PP1α only when phosphorylated at Thr320. This antibody may cross-react with the phosphorylated δ or γ isoforms of PP1.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr320 of human PP1α. Antibodies are purified by protein A and peptide affinity chromatography.
Western blot analysis of Recombinant PP1α, incubated with or without cdc2 protein kinase in the presence of ATP and kinase assay buffer at 30ºC for 30 minutes, using Phospho-PP1α (Thr320) Antibody (upper) or control PP1α Antibody #2582 (lower).
Western blot analysis of extracts from HeLa cells, asynchronous (lane 1), G2/M (lane 2) or released from G2/M for 6 hours (lane 3), using Phospho-PP1α (Thr320) Antibody (upper) or PP1α Antibody #2582 (lower).
Immunohistochemical analysis of paraffin-embedded human breast carcinoma, showing nuclear localization, using Phospho-PP1α (Thr320) Antibody.
Type 1 protein phosphatase (PP1), a serine/threonine phosphatase, is highly conserved in eukaryotic cells. Four isoforms of PP1 have been characterized: PP1α, PP1δ, PP1γ1 and PP1γ2 (1). Involvement in cell cycle regulation is one of the biological functions of PP1 (1). It has been illustrated that PP1 dephosphorylates Rb and cdc25 during mitosis (2,3). A cell cycle-dependent phosphorylation at Thr320 of PP1α by cdc2 kinase inhibits PP1α activity (4).
