Target Background

Function
The B regulatory subunit might modulate substrate selectivity and catalytic activity, and also might direct the localization of the catalytic enzyme to a particular subcellular compartment. Essential for serine/threonine-protein phosphatase 2A-mediated dephosphorylation of WEE1, preventing its ubiquitin-mediated proteolysis, increasing WEE1 protein levels, and promoting the G2/M checkpoint.

  1. Data show that SAM Domain and HD Domain-Containing Protein 1 (SAMHD1) is specifically targeted by protein phosphatase 2 regulatory subunit Balpha protein (PP2A-B55alpha) holoenzymes during mitotic exit. PMID: 29884836
  2. the data suggested that miR614 promoted cell proliferation and inhibited cell apoptosis of ovarian cancer (OC) cells by targeting PPP2R2A, and may therefore act as a potential target for OC therapy in the future. PMID: 29532877

  7. miR-222 targets protein phosphatase 2A subunit B in bladder cancer cells. PMID: 26800397
  8. miR-556-5p functions as an onco-miRNA and participates in prostate cancer carcinogenesis by suppressing PPP2R2A expression. PMID: 26297546
  9. Data show that breast cancer (BC) with PPP2R2A deletions are associated with worse overall survival, and the combination of altered PPP2R2A and high CCND1 expression define a subgroup of luminal-like BC patients with a high risk of relapse and death. PMID: 25879784
  10. overexpression of miR-892a may provide a selective growth promotion for colorectal cancer cells by direct suppression of PPP2R2A expression. PMID: 26054685
