BRK1 (Breakpoint cluster region kinase 1): BRK1 is a gene involved in signalling pathways that regulate cell proliferation, differentiation, and migration. As part of the breakpoint cluster region kinase family, BRK1 influences processes such as cell cycle progression, cytoskeletal organisation, and cell adhesion. It is also linked to immune regulation and oncogenic signalling, with dysregulation potentially contributing to cancer and inflammatory diseases.
