The FOXK1/MNF protein often called Forkhead Box K1 is a transcription factor that regulates gene expression linked to cell proliferation and differentiation. It has the molecular weight of approximately 84 kDa. Expressed in various tissues including muscle and brain FOXK1/MNF plays an essential role in regulating specific gene targets. The protein interacts with DNA via its forkhead domain influencing the transcriptional activity of numerous genes important for cellular functions.
Biological function summary

FOXK1/MNF is involved in the regulation of cell cycle progression and muscle regeneration. It forms part of a transcriptional complex that modulates gene expression to control these processes. In muscle tissue FOXK1/MNF influences the activation of satellite cells which are necessary for muscle repair and growth. This protein’s function in regulating cellular proliferation highlights its significance in tissue development and regeneration.

Pathways

The FOXK1/MNF protein is instrumental in the Wnt signaling and PI3K/AKT pathways. These pathways are significant for controlling cell proliferation differentiation and survival. Within these pathways FOXK1/MNF interacts with proteins such as beta-catenin in the Wnt signaling pathway. Through these interactions it modulates the transcription of genes responsible for various cellular functions further underlining its role in tissue regeneration and cancer development.

FOXK1/MNF links notably with certain cancers and muscular dystrophies. In cancer its overexpression can lead to unchecked cell proliferation and tumor growth interacting closely with proteins like PTEN a known tumor suppressor. In muscular dystrophy FOXK1/MNF may influence the disease progression by affecting the muscle regeneration process a vital element in maintaining muscle integrity. Understanding its expression and regulation can provide insights into the mechanisms driving these diseases and offer targets for potential therapeutic interventions.

Target data

Transcriptional regulator involved in different processes such as glucose metabolism, aerobic glycolysis, muscle cell differentiation and autophagy (By similarity). Recognizes and binds the forkhead DNA sequence motif (5'-GTAAACA-3') and can both act as a transcription activator or repressor, depending on the context (PubMed : 17670796). Together with FOXK2, acts as a key regulator of metabolic reprogramming towards aerobic glycolysis, a process in which glucose is converted to lactate in the presence of oxygen (By similarity). Acts by promoting expression of enzymes for glycolysis (such as hexokinase-2 (HK2), phosphofructokinase, pyruvate kinase (PKLR) and lactate dehydrogenase), while suppressing further oxidation of pyruvate in the mitochondria by up-regulating pyruvate dehydrogenase kinases PDK1 and PDK4 (By similarity). Probably plays a role in gluconeogenesis during overnight fasting, when lactate from white adipose tissue and muscle is the main substrate (By similarity). Involved in mTORC1-mediated metabolic reprogramming : in response to mTORC1 signaling, translocates into the nucleus and regulates the expression of genes associated with glycolysis and downstream anabolic pathways, such as HIF1A, thereby regulating glucose metabolism (By similarity). Together with FOXK2, acts as a negative regulator of autophagy in skeletal muscle : in response to starvation, enters the nucleus, binds the promoters of autophagy genes and represses their expression, preventing proteolysis of skeletal muscle proteins (By similarity). Acts as a transcriptional regulator of the myogenic progenitor cell population in skeletal muscle (By similarity). Binds to the upstream enhancer region (CCAC box) of myoglobin (MB) gene, regulating the myogenic progenitor cell population (By similarity). Promotes muscle progenitor cell proliferation by repressing the transcriptional activity of FOXO4, thereby inhibiting myogenic differentiation (By similarity). Involved in remodeling processes of adult muscles that occur in response to physiological stimuli (By similarity). Required to correct temporal orchestration of molecular and cellular events necessary for muscle repair (By similarity). Represses myogenic differentiation by inhibiting MEFC activity (By similarity). Positively regulates Wnt/beta-catenin signaling by translocating DVL into the nucleus (PubMed : 25805136). Reduces virus replication, probably by binding the interferon stimulated response element (ISRE) to promote antiviral gene expression (PubMed : 25852164). Accessory component of the polycomb repressive deubiquitinase (PR-DUB) complex; recruits the PR-DUB complex to specific FOXK1-bound genes (PubMed : 24634419, PubMed : 30664650).
