forkhead box K1

FOXK1 (Forkhead Box K1) is a Protein Coding gene. Diseases associated with FOXK1 include Contagious Pustular Dermatitis and Thyroid Angiosarcoma. Among its related pathways are Metabolism of proteins and CDK-mediated phosphorylation and removal of Cdc6. Gene Ontology (GO) annotations related to this gene include DNA binding transcription factor activity and RNA polymerase II transcription factor activity, sequence-specific DNA binding. An important paralog of this gene is FOXK2.

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).

Cytoplasm; Nucleus. Translocation to the nucleus is regulated by phosphorylation: phosphorylation by GSK3 (GSK3A or GSK3B) promotes interaction with 14-3-3 proteins and sequestration in the cytoplasm. Dephosphorylation promotes translocation to the nucleus (By similarity). Accumulates in the nucleus upon viral infection (PubMed:25852164).

Phosphorylation by GSK3 (GSK3A or GSK3B) promotes interaction with YWHAE/14-3-3-epsilon and retention in the cytoplasm. In response to mTORC1 signaling, phosphorylation by GSK3 is prevented, leading to translocation to the nucleus.
