High impact information on PPP1R7

  • However, we did find evidence of downregulated gene expression in CFLAR, CASP10 and PPP1R7 in CC cell lines [1].
  • Northern analysis revealed a major transcript of 1.39 kb in all 8 investigated human tissues. sds22 was detected by western analysis in both the cytoplasm and the nucleus of rat liver cells as a polypeptide of 44 kDa [2].
  • sds22 is a regulatory polypeptide of protein phosphatase-1 that is required for the completion of mitosis in both fission and budding yeast [2].
  • The human homolog of sds22 consists of 360 residues, has a calculated molecular mass of 41.6 kDa and shows a tandem array of 11 leucine-rich repeat structures of 22 residues [2].
  • Possible missense mutations of the PPP1R5, PPP1R7 and PPP1R8 genes were detected in one (2%), two (4%) and one (2%) cell line, respectively [3].
