eyes absent Activators

The realm of eyes absent (Eya) protein activators is rooted in the intricate interactions of signaling pathways that influence its function. Eya, known for its phosphatase activity and role as a transcriptional co-activator, operates in tandem with an array of cellular processes, most prominently the Hippo signaling pathway. Verteporfin and XMU-MP-1, for instance, modulate components of the Hippo pathway, thereby influencing the activity and interactions of Eya. By disrupting the YAP-TEAD interaction or inhibiting MST1/2 kinases, these compounds can lead to an upregulation of YAP/TAZ activity, resulting in a change in the interaction dynamics of Eya within the cellular environment.

Another facet of Eya activation delves into the crosstalk of the Hippo pathway with other signaling cascades. Compounds like Dorsomorphin, CHIR-99021, and Y-27632 exemplify this interplay by targeting BMP signaling, Wnt/β-catenin signaling, or Rho-associated protein kinases respectively. Each of these molecules, by acting on their primary targets, indirectly shift the balance of Hippo signaling, influencing Eya's function. Additionally, the interplay between mTOR signaling, as seen with compounds OSI-027, KU-0063794, and AZD8055, and the Hippo pathway further illustrates the nuanced layers of interactions that can modulate Eya. Every compound, in its unique manner, tweaks the signaling dynamics in the cellular environment, leading to an indirect influence on Eya's role in organogenesis and other developmental processes.
