  • Relevance
    PPP1R10 (serine/threonine protein phosphatase 1 regulatory subunit 10), also known as PNUTS, is a targeting subunit of protein phosphatase 1 (PP1). Furthermore, PPP1R10 acts as an inhibitor of PPP1CA and PPP1CC phosphatase activities. Its inhibitory activity on PPP1CA is only observed when PPP1R10 is phosphorylated by Protein Kinase A (PKA). PPP1R10 contains a zinc finger motif and is predominantly localised within the nucleus. Recently, PPP1R10 has been shown to target PP1 to GABA(C) receptors, shuttling from the nucleus to the cell membrane in cells co-expressing this receptor. This highlights a role for this protein in the regulation of synaptic signal transduction. PPP1R10 has also been shown to regulate the activity of p53 in response to hypoxia.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human prostate carcinoma tissue labelling PPP1R10 with ab70247 at 1/1000 (1µg/ml). Detection: DAB.
  • Lanes 1-2 : Anti-PPP1R10 antibody (ab70247) at 1 µg/ml
    Lanes 3-4 : Anti-PPP1R10 antibody (ab70247) at 0.2 µg/ml

    Lanes 1 & 3 : Nuclear extract from Hela cells at 15 µg
    Lanes 2 & 4 : Nuclear extract from Hela cells at 45 µg

    Predicted band size: 99 kDa
    Observed band size: 115 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 48 kDa. We are unsure as to the identity of these extra bands.
