LRRC42, short for Leucine-rich repeat-containing protein 42, is a member of the leucine-rich repeat (LRR) protein family, characterized by its unique structural motif composed of repeating sequences rich in leucine residues. Positioned predominantly within the cytoplasm or on the cell membrane, LRRC42 plays various roles in cellular processes, including signal transduction, protein-protein interactions, and cell adhesion. One of the distinctive features of LRRC42 is its involvement in protein-protein interactions mediated by its leucine-rich repeat domains. These domains serve as interaction interfaces, allowing LRRC42 to bind to specific partner proteins involved in diverse cellular pathways. By participating in these interactions, LRRC42 can...
