... ganglion cell function as well as photoreceptor homeostasis. In particular work from flies and zebrafish has highlighted the role of the E3 ligase enzyme family, Seven in Absentia Homologue (Siah) during these events. In this review, we summarize the current understanding of UPS activity during Drosophila...

... of the isopeptidic bond between the lysine substrate and the C-terminus of SUMO. In particular, we will focus on the recent discoveries on the catalytic function of the SUMO E3 ligases revealed by structural and biochemical approaches. Also, we will discuss important questions regarding specificity in SUMO...

... be recognized by proteins containing multiple SIMs. One protein that contains such a sequence of SIMs also contains a RING (really interesting new gene) domain that is the hallmark of a ubiquitin E3 ligase. This ubiquitin ligase known as RNF4 (RING finger protein 4) has the unique property that it can recognize...

... on understanding the role of these proteins as key regulators of mRNA turnover, the requirement for E3 ligase activity in mRNA decay remains unclear. It is remarkable that the ubiquitin system is involved, either directly or indirectly, in both the degradation of nucleic acids as well as proteins. These new RNA...

...Gemma Marfany; Amanda Denuc Ub (ubiquitin) and Ubls (Ub-like molecules) are peptide modifiers that change the fate and function of their substrates. A plethora of enzyme activities and protein cofactors are required for either the conjugation (mainly E3 ligases) or deconjugation of Ub and Ubls...

... of the SUMO pathway is through targeting the E3 ligases, and a number of different ways to achieve this have been identified. More generally, the MAPK (mitogen-activated protein kinase) pathways represent one way through which SUMOylation of specific proteins is controlled, by using molecular mechanisms...
