LRRC42 (Leucine-rich repeat-containing protein 42):LRRC42 is a gene that encodes a protein belonging to the leucine-rich repeat (LRR) family, characterized by repeating sequences rich in leucine residues. Predominantly located in the cytoplasm or on the cell membrane, LRRC42 is involved in cellular processes such as signal transduction, protein-protein interactions, and cell adhesion. Its LRR domains serve as interaction interfaces, enabling LRRC42 to bind specific partner proteins and participate in diverse cellular pathways.
