BRK1 (Breakpoint cluster region kinase 1): BRK1 is a gene involved in signaling 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 organization, and cell adhesion. It is also linked to immune regulation and oncogenic signaling, with dysregulation potentially contributing to cancer and inflammatory diseases.
