    CATEGORY regulatory , tumor suppressor
  • co-localizes with PITX2 in nucleus
  • shuttling from the cytoplasm to the nucleus is essential for RASSF2 function
  • basic FUNCTION
  • PKC apoptosis WT1 regulator
  • transcriptional repressor activity
  • contributes to apoptotic neuronal cell death in Alzeihmer disease
  • regulated choline up-take via its interaction with CHT1
  • may be a mediator of neuronal apoptosis in HIV encephalitis
  • regulatory component in the dopamine signaling, constituting a molecular link between impaired dopamine signaling and depression
  • in addition to its proapoptotic function, acts as a novel transcription cofactor for AR to target CFLAR gene expression
  • proapoptotic protein with intracellular functions in the cytoplasm and nucleus
  • activates an extrinsic pathway involving cell surface HSPA5 for induction of apoptosis and is essential for its cell surface expression
  • PITX2-interacting protein that regulates PITX2 activity in ocular cells
  • unique proapoptotic protein that selectively induces apoptosis in cancer cells, sensitizes cells to the action of multiple apoptotic stimuli, and causes tumor regression through a region harboring 59-AAs starting from 145 to 203
  • act at multiple levels that include activating both the FAS- and tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL)-controlled proapoptotic pathways, as well as inhibiting the NF-{kappa}B antiapoptotic pathway
  • implicated in the regulation of smooth muscle contraction
  • is expressed in trophoblastic cells and is involved in transport of HSPA5 to the cell surface and thus regulates invasive property of extravillous cytotrophoblastic cells (CTB)
  • is a novel and essential downstream target of TGFB1 signaling and acts as an important factor during TGFB1-induced EMT
  • importance of PAWR not only in preventing cancer development/recurrence but also as a promising anticancer therapeutic agent

    small molecule
  • interacts with numerous proteins such as WT1, atypical protein kinase C (aPKC)
  • interacting with THAP1 in primary endothelial cells and fibroblasts
  • interacting with CHT1
  • interacting with HIV-1 Tat

  • cooperation between PAWR and PTEN as relevant for the development of prostate cancer and implicate the NF-kappaB pathway as a critical event in prostate tumorigenesis
  • PITX2-interacting protein that regulates PITX2 transcriptional activity in ocular cells (interaction between PITX2 and PAWR might have a role in apoptotic and/or neurodegeneration pathways involved in glaucoma)
  • is a novel substrate of CASP3 during apoptosis (the novel specific CASP3 cleavage site in PAWR, and the cleaved fragment of PAWR retains proapoptotic activity)
  • phosphorylation of PAWR at Thr155 disrupts its interaction with PPP1R12A, exposing the sites of phosphorylation in PPP1R12A and leading to myosin light chain phosphatase inhibition and contraction
  • role of X-linked inhibitor of apoptosis protein in the regulation of endogenous PAWR levels through inhibition of caspase-mediated cleavage
  • TNF-induced apoptosis leads to CASP8-dependent PAWR-cleavage followed by nuclear accumulation of the C-terminal PAWR (132-340) fragment, which then induces apoptosis
  • FBXO45 interacts with PAWR in the cytoplasm and mediates its ubiquitylation and proteasomal degradation
  • TRIM21 is a novel interacting partner of PAWR, and interact with PAWR endogenously and through its PRY-SPRY domain
  • FOXO3 directly binds to the PAWR promoter and activates its transcription following inhibition of the PI3K-AKT pathway

    Therapy target
    activation of PAWR by small activating RNAs may have a therapeutic benefit for prostate and other types of cancer
    identification of an extracellular role for PAWR and its SAC domain significantly broadens their therapeutic potential for primary and metastatic tumors
    is likely a very interesting therapeutic target against ovarian carcinogenesis
