Abstract

The Yes-associated protein (YAP) transcription coactivator is a key regulator of organ size and a candidate human oncogene. YAP is inhibited by the Hippo pathway kinase cascade, at least in part via phosphorylation of Ser 127, which results in YAP 14–3–3 binding and cytoplasmic retention. Here we report that YAP is phosphorylated by Lats on all of the five consensus HXRXXS motifs. Phosphorylation of Ser 381 in one of them primes YAP for subsequent phosphorylation by CK1δ/ɛ in a phosphodegron. The phosphorylated phosphodegron then recruits the SCF β-TRCP E3 ubiquitin ligase, which catalyzes YAP ubiquitination, ultimately leading to YAP degradation. The phosphodegron-mediated degradation and the Ser 127 phosphorylation-dependent translocation coordinately suppress YAP oncogenic activity. Our study identified CK1δ/ɛ as new regulators of YAP and uncovered an intricate mechanism of YAP regulation by the Hippo pathway via both S127 phosphorylation-mediated spatial regulation (nuclear–cytoplasmic shuttling) and the phosphodegron-mediated temporal regulation (degradation).

  • YAP contains a phosphodegron, so decreased YAP phosphorylation leads to YAP accumulation and nuclear translocation.

    “YAP bears a phosphodegron so decreased YAP phosphorylation leads to YAP accumulation and eventual translocation into the nucleus where it drives transcription of tumor-promoting genes (Figure 5) [106].”

    From Acetylation: a new target for protein degradation in cancer (2025) · cites this paper as [106]

    The Abstract (page unavailable) identifies a YAP phosphodegron and says its phosphorylation promotes YAP degradation; it separately links Ser127 phosphorylation to cytoplasmic retention. The Spatial and temporal regulation of YAP section (page unavailable) likewise treats degradation and nuclear–cytoplasmic localization as distinct mechanisms. The source therefore supports the broad effect of reduced phosphorylation on YAP accumulation and nuclear activity, but not the sentence’s implication that phosphodegron phosphorylation itself controls nuclear translocation or its specific claim about transcription of tumor-promoting genes. (LLM, conf=0.84)

  • Nuclear YAP drives transcription of tumor-promoting genes.

    “YAP bears a phosphodegron so decreased YAP phosphorylation leads to YAP accumulation and eventual translocation into the nucleus where it drives transcription of tumor-promoting genes (Figure 5) [106].”

    From Acetylation: a new target for protein degradation in cancer (2025) · cites this paper as [106]

    The paper describes YAP as a transcription coactivator and human oncogene, and the Spatial and temporal regulation of YAP section says phosphorylation keeps it apart from nuclear transcription factors such as TEAD (page not provided). This supports a role for nuclear YAP in transcription, but our copy does not establish that the genes it helps transcribe are tumor-promoting. (LLM, conf=0.78)

  • Phosphorylated Lats1 and Lats2 inhibit Yap and Taz by phosphorylating multiple serine residues.

    “Phosphorylated Lats1 and Lats2 then inhibit the transcriptional co-factors Yap and Taz by phosphorylating multiple serine residues (86, 162).”

    From The Hippo signal transduction network for exercise physiologists (2016) · cites this paper as [162]

    The section “YAP is phosphorylated in vivo on multiple sites” identifies five YAP serines at Lats consensus sites, and the paper describes Lats-mediated inhibition of YAP. The passages do not establish the same phosphorylation-and-inhibition claim for TAZ. No page numbers were provided in our copy. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • In AMG510 resistant cell line NCI-H1792, AMG510 caused dose-dependent decreases in Phospho YAP S127-total YAP ratio.

    “Experiments with the AMG510 resistant cell line NCI‐H1792 revealed AMG510 dose‐dependent decreases in the Phospho YAP S127‐total YAP ratio, which is commonly used as a negative marker for YAP signaling[ 34 ] (Figure 5B,C; Figure S6C,D, Supporting Information).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
