The Role of E3 Ligase Pirh2 in Disease
Cells, 2022 The p53-dependent ubiquitin ligase Pirh2 regulates a number of proteins involved in different cancer-associated processes. Targeting the p53 family proteins, Chk2, p27Kip1, Twist1 and others, Pirh2 participates in such cellular processes as proliferation, cell cycle regulation, apoptosis and cellular migration.

Progress on Poxvirus E3 Ubiquitin Ligases and Adaptor Proteins
Frontiers in Immunology, 2021 Poxviruses have evolved a variety of innate immunity evasion mechanisms, some of which involve poxvirus-encoded E3 ubiquitin ligases and adaptor proteins.

IAPs as E3 ligases of Rac1 [PDF]
Small GTPases, 2012 Inhibitors of Apoptosis Proteins (IAPs) are well-studied E3 ubiquitin ligases predominantly known for regulation of apoptosis. We uncovered that IAPs can function as a direct E3 ubiquitin ligase of RhoGTPase Rac1. cIAP1 and XIAP directly conjugate polyubiquitin chains to Lysine 147 of activated Rac1 and target it for proteasomal degradation ...

RING Domain E3 Ubiquitin Ligases
Annual Review of Biochemistry, 2009 E3 ligases confer specificity to ubiquitination by recognizing target substrates and mediating transfer of ubiquitin from an E2 ubiquitin-conjugating enzyme to substrate. The activity of most E3s is specified by a RING domain, which binds to an E2∼ubiquitin thioester and activates discharge of its ubiquitin cargo.

The Role of HECT E3 Ubiquitin Ligases in Colorectal Cancer
Biomedicines, 2023 Colorectal cancer (CRC) is estimated to rank as the second reason for cancer-related deaths, and the prognosis of CRC patients remains unsatisfactory. Numerous studies on gastrointestinal cell biology have shown that the E3 ligase-mediated ubiquitination

AIRE Functions As an E3 Ubiquitin Ligase [PDF]
The Journal of Experimental Medicine, 2004 Autoimmune regulator (AIRE) gene mutation is responsible for the development of autoimmune-polyendocrinopathy-candidiasis ectodermal dystrophy, an organ-specific autoimmune disease with monogenic autosomal recessive inheritance. AIRE is predominantly expressed in medullary epithelial cells of the thymus and is considered to play important roles in the ...

Science-Business eXchange, 2010 Two groups of researchers have identified inhibitors of E3 ubiquitin ligase, which has been considered difficult, if not impossible, to target with small molecules. The findings could lead to compounds that are more specific disrupters of tumor cell proliferation than the proteasome inhibitor Velcade bortezomib.

Activation of the E3 ubiquitin ligase Parkin [PDF]
Biochemical Society Transactions, 2015 The PINK1 (phosphatase and tensin homologue-induced putative kinase 1)/Parkin-dependent mitochondrial quality control pathway mediates the clearance of damaged organelles, but appears to be disrupted in Parkinson's disease (PD) [Springer and Kahle (2011) Autophagy 7, 266–278].
