MLP Assay (1)

AID Type Active / Inconclusive / Inactive Description
624438 confirmatory 0 / 0 / 1 Late stage assay provider counterscreen for the probe development effort to identify inhibitors of PP5: fluorescence-based biochemical dose response assay to determine activity of inhibitors on dephosphorylation of OMFP by PP2C-alpha (Round 5)

Gene RIF (20)

25815785 findings demonstrate a novel regulatory circuit in which STING and TBK1 reciprocally regulate each other to enable efficient antiviral signaling activation, and PPM1A dephosphorylates STING and TBK1
25026293 Loss of PPM1A is associated with the development of tumor invasion in bladder cancer patients.
24901250 The TGF-beta/Smad signaling system decreases its activity through strong negative regulation. We provide evidence for a new negative feedback loop through PPM1A upregulation.
23906386 phosphatase activity toward phosphopeptide substrates by PP2Calpha and Wip1 requires the binding of a Mg(2)+ ion to the low-affinity site.
23812431 PPM1A is a RelA phosphatase that regulates NF-kappaB activity and that PPM1A has tumor suppressor-like activity.
23779087 a nuclear envelope-localized mechanism of inactivating TGF-beta signaling in which MAN1 competes with transcription factors for binding to Smad2 and Smad3 and facilitates their dephosphorylation by PPM1A.
23560844 PPM1A negatively regulates ERK by directly dephosphorylating its pThr202 position early in epidermal growth factor stimulation. Additional kinetic studies reveal that key residues participate in phospho-ERK recognition by PPM1A.
22727189 PPM1A inhibits HIV-1 infection and gene expression. PPM1A depletion in resting CD4+ T cells increases HIV-1 gene expression.
22727189 Knockdown of protein phosphatase, Mg2+/Mn2+ dependent, 1A (PPM1A) by siRNA ehnahces HIV-1 gene expression in resting CD4+ T cells
22519956 Studies indicate that phosphatase PPM1G is a component of the spliceosome and binds to protein YB-1 to affect alternative splicing.
