Abstract Background LNX (Ligand of Numb Protein-X) proteins typically contain an amino-terminal RING domain adjacent to either two or four PDZ domains - a domain architecture that is unique to the LNX family. LNX proteins function as E3 ubiquitin ligases and their domain organisation suggests that their ubiquitin ligase activity may be targeted to specific substrates or subcellular lo... https://www.bekindtopets.com/limited-offer-Silver-Lining-Herbs-Kidney-Support-super-offer/
