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. Primarily 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 act as interaction interfaces, allowing LRRC42 to bind specific partner proteins and engage in various cellular pathways.
