Six signal transduction system, notch, EGF, FGF, TGFbeta, Hedgehog, and Wnt, are utilized to provide spatial inputs in a myriad of diverse subcircuits in the development of any bilaterian, and in different contents in different bilaterians. Though in their internal biochemical interactions these signal transduction cassetes are higly conserved across the bilateria, they are indeed "plugged in" at all levels of gene regulatory networks, in all sorts of regulatory spatial specification processes.

.. a small set of intercellular signal systems used in developmental, specification processes: for example throughout the bilaterian world Hedgehog, TGFbeta, Wnt, FGF and Notch signaling cassettes are utilized and reutilized in diverse developmental contexts.
The cassette includes in each case the genes ( and their regulatory modules) encoding ligands, the receptors, and the transcription factors which provide the immediaty early responses used to transduce the intercellular signal at the transcription level in the cell expressing the receptor.
In each of these signaling systems the cassettes are largely invariant in their orthologous molecular constitutions, as they appear in different bilaterians, but their target cis-regulatory modules occur in as great variety as the diversity of the jobs they do. Thus the distinction betwen the plug-in and the device into which it is plugged is not in the least obscure.

Deubiquitinase USP10 regulates Notch signaling in the endothelium.Abstract
Notch signaling is a core patterning module
for vascular morphogenesis that codetermines the sprouting behavior of
endothelial cells (ECs). Tight quantitative and temporal control of Notch activity is essential for vascular development, yet the details of Notch
regulation in ECs are incompletely understood.
We found that
ubiquitin-specific peptidase 10 (USP10) interacted with the NOTCH1
intracellular domain (NICD1) to slow the ubiquitin-dependent turnover of
this short-lived form of the activated NOTCH1 receptor.
Accordingly,
inactivation of USP10 reduced NICD1 abundance and stability and
diminished Notch-induced target gene expression in ECs.
In mice, the loss of endothelial Usp10
increased vessel sprouting and partially restored the patterning
defects caused by ectopic expression of NICD1. Thus, USP10 functions as
an NICD1 deubiquitinase that fine-tunes endothelial Notch responses during angiogenic sprouting.
