This is what the bacterial LPX-E3 ligases
- which can penetrate into the cell without any aid and can act intracellularly - are designed to prevent.
elegans, multiple ubiquitin ligases
have been implicated in UPS-dependent regulation of AMPAR synaptic abundance, including the anaphase-promoting complex (APC) , CUL3/KEL-8 , and RPM-1 .
Nurix's technology platform is focused on the manipulation of the ubiquitin system and its component E3 ligases
, the key enzymes responsible for controlling protein levels in human cells.
Under the multi-year collaboration, Nurix will utilize its proprietary drug discovery platform to identify novel agents that utilize E3 ligases
to induce degradation of specified drug targets and Gilead will have an option to license drug candidates directed to up to five targets resulting from the work.
Towards the end of the defense process, transcription factors (WRKY and MYB) and regulatory enzyme such as E3 ubiquitin ligases
will regulate the expression of defense-associated genes (18-31).
Of key relevance in the proteasome system are the so-called E3-ubiquitin ligases
. These enzymes mark proteins for degradation to keep the cells in a healthy state.

Ja em relacao as vias de degradacao, destaca-se a via proteassomal, representada pelo sistema ubiquitina-proteassoma, que age de forma seletiva na proteolise muscular, atuando de forma importante no processo atrofico atraves da sinalizacao de duas ligases
chave desse sistema, conhecidas como MURF-1 e MAFBx.
