Forkhead box protein K2 (FOXK2)

Forkhead box protein K2 (FOXK2) is a transcription factor belonging to the forkhead family, characterized by a conserved forkhead (FKH) DNA-binding domain. FOXK2 regulates gene expression by binding specific DNA motifs, recruits chromatin-modifying complexes, and acts as a scaffold for co-regulators. It controls diverse processes such as cell proliferation, cell cycle progression, DNA repair, and embryonic development. Altered FOXK2 function or expression has been implicated in various cancers, where it can act as both a tumor suppressor and promoter, depending on context. It interacts with partners including AP-1, BAP1, ERα, and DVL, influencing signaling pathways like Wnt and estrogen receptor signaling. There are currently no direct drugs available for FOXK2, but its broad involvement in oncogenesis and cell fate regulation makes it a significant molecular target of interest for future therapeutic development[1][2][3].
