Function
Catalyzes the final rate-limiting step of glycolysis by mediating the transfer of a phosphoryl group from phosphoenolpyruvate (PEP) to ADP, generating ATP (PubMed:15996096, PubMed:1854723, PubMed:20847263). The ratio between the highly active tetrameric form and nearly inactive dimeric form determines whether glucose carbons are channeled to biosynthetic processes or used for glycolytic ATP production (PubMed:15996096, PubMed:1854723, PubMed:20847263). The transition between the 2 forms contributes to the control of glycolysis and is important for tumor cell proliferation and survival (PubMed:15996096, PubMed:1854723, PubMed:20847263). {ECO:0000269|PubMed:15996096, ECO:0000269|PubMed:1854723, ECO:0000269|PubMed:20847263}.; [Isoform M2]: Isoform specifically expressed during embryogenesis that has low pyruvate kinase activity by itself and requires allosteric activation by D-fructose 1,6-bisphosphate (FBP) for pyruvate kinase activity (PubMed:18337823, PubMed:20847263). In addition to its pyruvate kinase activity in the cytoplasm, also acts as a regulator of transcription in the nucleus by acting as a protein kinase (PubMed:18191611, PubMed:21620138, PubMed:22056988, PubMed:22306293, PubMed:22901803, PubMed:24120661). Translocates into the nucleus in response to various signals, such as EGF receptor activation, and homodimerizes, leading to its conversion into a protein threonine- and tyrosine-protein kinase (PubMed:22056988, PubMed:22306293, PubMed:22901803, PubMed:24120661, PubMed:26787900). Catalyzes phosphorylation of STAT3 at 'Tyr-705' and histone H3 at 'Thr-11' (H3T11ph), leading to activate transcription (PubMed:22306293, PubMed:22901803, PubMed:24120661). Its ability to activate transcription plays a role in cancer cells by promoting cell proliferation and promote tumorigenesis (PubMed:18337823, PubMed:22901803, PubMed:26787900). Promotes the expression of the immune checkpoint protein CD274 in BMAL1-deficient macrophages (By similarity). May also act as a translation regulator for a subset of mRNAs, independently of its pyruvate kinase activity: associates with subpools of endoplasmic reticulum-associated ribosomes, binds directly to the mRNAs translated at the endoplasmic reticulum and promotes translation of these endoplasmic reticulum-destined mRNAs (By similarity). Plays a role in caspase independent cell death of tumor cells (PubMed:17308100). {ECO:0000250|UniProtKB:P52480, ECO:0000269|PubMed:17308100, ECO:0000269|PubMed:18191611, ECO:0000269|PubMed:18337823, ECO:0000269|PubMed:20847263, ECO:0000269|PubMed:21620138, ECO:0000269|PubMed:22056988, ECO:0000269|PubMed:22306293, ECO:0000269|PubMed:22901803, ECO:0000269|PubMed:24120661, ECO:0000269|PubMed:26787900}.; [Isoform M1]: Pyruvate kinase isoform expressed in adult tissues, which replaces isoform M2 after birth (PubMed:18337823). In contrast to isoform M2, has high pyruvate kinase activity by itself and does not require allosteric activation by D-fructose 1,6-bisphosphate (FBP) for activity (PubMed:20847263). {ECO:0000269|PubMed:18337823, ECO:0000269|PubMed:20847263}.

Nucleus {ECO:0000269|PubMed:17308100, ECO:0000269|PubMed:18191611, ECO:0000269|PubMed:22056988, ECO:0000269|PubMed:22901803, ECO:0000269|PubMed:24120661, ECO:0000269|PubMed:26787900, ECO:0000269|PubMed:27573352, ECO:0000269|PubMed:32268273}. Note=Translocates to the nucleus in response to various signals, such as EGF receptor activation or apoptotic stimuli (PubMed:17308100, PubMed:22056988, PubMed:24120661). Nuclear translocation is promoted by acetylation by EP300 (PubMed:24120661). Deacetylation by SIRT6 promotes its nuclear export in a process dependent of XPO4, thereby suppressing its ability to activate transcription and promote tumorigenesis (PubMed:26787900). {ECO:0000269|PubMed:17308100, ECO:0000269|PubMed:22056988, ECO:0000269|PubMed:24120661, ECO:0000269|PubMed:26787900}.; [Isoform M1]: Cytoplasm {ECO:0000305}.
Tissues
[Isoform M2]: Specifically expressed in proliferating cells, such as embryonic stem cells, embryonic carcinoma cells, as well as cancer cells. {ECO:0000269|PubMed:18191611, ECO:0000269|PubMed:18337823}.; [Isoform M1]: Expressed in adult tissues (PubMed:18337823). Not expressed in tumor cells (PubMed:18337823). {ECO:0000269|PubMed:18337823}.
Structure
[Isoform M2]: Monomer and homotetramer; exists as a monomer in the absence of D-fructose 1,6-bisphosphate (FBP), and reversibly associates to form a homotetramer in the presence of FBP (PubMed:15996096, PubMed:18298799, PubMed:18337815, PubMed:1854723, PubMed:23064226, PubMed:2813362). The monomeric form binds 3,3',5-triiodo-L-thyronine (T3) (PubMed:15996096). Tetramer formation induces pyruvate kinase activity (PubMed:15996096, PubMed:18298799, PubMed:18337815, PubMed:1854723, PubMed:23064226, PubMed:2813362). The tetrameric form has high affinity for the substrate and is associated within the glycolytic enzyme complex (PubMed:15996096, PubMed:18298799, PubMed:18337815, PubMed:1854723, PubMed:23064226, PubMed:2813362). FBP stimulates the formation of tetramers from dimers (PubMed:15996096, PubMed:18298799, PubMed:18337815, PubMed:1854723, PubMed:23064226, PubMed:2813362). Homodimer; exists in a dimeric form in tumor cells and the dimeric form has less affinity for the phosphoenolpyruvate substrate (PubMed:22306293, PubMed:24120661). The homodimer converts into a protein kinase (PubMed:22306293, PubMed:24120661). Interacts with HERC1, POU5F1 and PML (PubMed:12650930, PubMed:18191611). Interacts with EGLN3; the interaction hydroxylates PKM under hypoxia and enhances binding to HIF1A (PubMed:21483450, PubMed:21620138). Interacts with HIF1A; the interaction is enhanced by binding of EGLN3, promoting enhanced transcription activity under hypoxia (PubMed:21620138). Interacts with TRIM35; this interaction prevents FGFR1-dependent tyrosine phosphorylation (PubMed:25263439). Interacts with JMJD8 (PubMed:27199445). Interacts with TRAF4 (PubMed:32268273). Interacts with (phosphorylated) CTNNB1; leading to activate transcription (PubMed:22056988). Interacts with TSC22D2; the interaction results in reduced nuclear levels of PKM isoform M2, leading to repression of cyclin CCND1 transcription and reduced cell growth (PubMed:27573352). {ECO:0000269|PubMed:12650930, ECO:0000269|PubMed:15996096, ECO:0000269|PubMed:18191611, ECO:0000269|PubMed:18298799, ECO:0000269|PubMed:18337815, ECO:0000269|PubMed:1854723, ECO:0000269|PubMed:21483450, ECO:0000269|PubMed:21620138, ECO:0000269|PubMed:22056988, ECO:0000269|PubMed:22306293, ECO:0000269|PubMed:23064226, ECO:0000269|PubMed:24120661, ECO:0000269|PubMed:25263439, ECO:0000269|PubMed:27199445, ECO:0000269|PubMed:27573352, ECO:0000269|PubMed:2813362, ECO:0000269|PubMed:32268273}.; (Microbial infection) Binding to certain oncoproteins such as HPV-16 E7 oncoprotein promotes homodimerization. {ECO:0000269|PubMed:24120661}.
