Multivalent Angiomotin-like 1 and Yes-associated protein form a dynamic complex.
Article in Protein science : a publication of the Protein Society, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Multivalent complexes formed between the cancer-promoting transcriptional co-activator, Yes-associated protein (YAP), and proteins containing short linear motifs of type PPxY modulate cell proliferation and are attractive therapeutic targets. However, challenges producing PPxY polypeptides containing the full binding domain has limited understanding of the assembly process. Here, we successfully produced a polypeptide containing the complete set of three PPxY binding sites of Angiomotin-like 1 (AMOTL1), a scaffolding protein that regulates the nucleo-cytoplasmic shuttling of YAP via WW-PPxY interactions. Using an array of biophysical techniques including isothermal titration calorimetry, size-exclusion chromatography coupled to multi-angle light scattering, and solution nuclear magnetic resonance spectroscopy, we show that the AMOTL1 polypeptide is partially disordered, and binds the YAP WW domains to form an ensemble of complexes of varying stabilities. The binding process is initiated by the binding of one YAP WW domain to one AMOTL1 PPxY motif and is completed by transient interactions of the second YAP WW domain with a second AMOTL1 PPxY motif to form an equilibrating mixture composed of various species having two YAP sites bound to two conjugate AMOTL1 sites. We rationalize that the transient interactions fine-tune the stability of the complex for rapid assembly and disassembly in response to changes in the local cellular environment.
