CC -!- FUNCTION: Catalyzes the final rate-limiting step of glycolysis by
CC mediating the transfer of a phosphoryl group from phosphoenolpyruvate
CC (PEP) to ADP, generating ATP. The ratio between the highly active
CC tetrameric form and nearly inactive dimeric form determines whether
CC glucose carbons are channeled to biosynthetic processes or used for
CC glycolytic ATP production. The transition between the 2 forms
CC contributes to the control of glycolysis and is important for tumor
CC cell proliferation and survival. {ECO:0000250|UniProtKB:P14618}.
CC -!- FUNCTION: [Isoform M2]: Isoform specifically expressed during
CC embryogenesis that has low pyruvate kinase activity by itself and
CC requires allosteric activation by D-fructose 1,6-bisphosphate (FBP) for
CC pyruvate kinase activity. In addition to its pyruvate kinase activity
CC in the cytoplasm, also acts as a regulator of transcription in the
CC nucleus by acting as a protein kinase. Translocates into the nucleus in
CC response to various signals, such as EGF receptor activation, and
CC homodimerizes, leading to its conversion into a protein threonine- and
CC tyrosine-protein kinase. Catalyzes phosphorylation of STAT3 at 'Tyr-
CC 705' and histone H3 at 'Thr-11' (H3T11ph), leading to activate
CC transcription. Its ability to activate transcription plays a role in
CC cancer cells by promoting cell proliferation and promote tumorigenesis
CC (By similarity). Promotes the expression of the immune checkpoint
CC protein CD274 in ARNTL/BMAL1-deficient macrophages. May also act as a
CC translation regulator for a subset of mRNAs, independently of its
CC pyruvate kinase activity: associates with subpools of endoplasmic
CC reticulum-associated ribosomes, binds directly to the mRNAs translated
CC at the endoplasmic reticulum and promotes translation of these
CC endoplasmic reticulum-destined mRNAs (By similarity). Plays a role in
CC caspase independent cell death of tumor cells (By similarity).
CC {ECO:0000250|UniProtKB:P14618, ECO:0000250|UniProtKB:P52480}.
CC -!- FUNCTION: [Isoform M1]: Pyruvate kinase isoform expressed in adult
CC tissues, which replaces isoform M2 after birth. In contrast to isoform
CC M2, has high pyruvate kinase activity by itself and does not require
CC allosteric activation by D-fructose 1,6-bisphosphate (FBP) for
CC activity. {ECO:0000250|UniProtKB:P14618}.

CC -!- ACTIVITY REGULATION: [Isoform M2]: Isoform M2 is allosterically
CC activated by D-fructose 1,6-bisphosphate (FBP). Inhibited by oxalate
CC and 3,3',5-triiodo-L-thyronine (T3). The activity of the tetrameric
CC form is inhibited by PML. Selective binding to tyrosine-phosphorylated
CC peptides releases the allosteric activator FBP, leading to inhibition
CC of PKM enzymatic activity, this diverts glucose metabolites from energy
CC production to anabolic processes when cells are stimulated by certain
CC growth factors. Glycolytic flux are highly dependent on de novo
CC biosynthesis of serine and glycine, and serine is a natural ligand and
CC allosteric activator of isoform M2. {ECO:0000250|UniProtKB:P14618}.
CC -!- ACTIVITY REGULATION: [Isoform M1]: Has high pyruvate kinase activity by
CC itself and does not require allosteric activation by D-fructose 1,6-
CC bisphosphate (FBP) for activity. {ECO:0000250|UniProtKB:P14618}.
CC -!- PATHWAY: Carbohydrate degradation; glycolysis; pyruvate from D-
CC glyceraldehyde 3-phosphate: step 5/5. {ECO:0000250|UniProtKB:P14618}.
CC -!- SUBUNIT: [Isoform M2]: Monomer and homotetramer; exists as a monomer in
CC the absence of D-fructose 1,6-bisphosphate (FBP), and reversibly
CC associates to form a homotetramer in the presence of FBP. The monomeric
CC form binds 3,3',5-triiodo-L-thyronine (T3). Tetramer formation induces
CC pyruvate kinase activity. The tetrameric form has high affinity for the
CC substrate and is associated within the glycolytic enzyme complex. FBP
CC stimulates the formation of tetramers from dimers. Homodimer; exists in
CC a dimeric form in tumor cells and the dimeric form has less affinity
CC for the phosphoenolpyruvate substrate. The homodimer converts into a
CC protein kinase. Interacts with HERC1, POU5F1 and PML. Interacts with
CC EGLN3; the interaction hydroxylates PKM under hypoxia and enhances
CC binding to HIF1A. Interacts with HIF1A; the interaction is enhanced by
CC binding of EGLN3, promoting enhanced transcription activity under
CC hypoxia. Interacts with TRIM35; this interaction prevents FGFR1-
CC dependent tyrosine phosphorylation. Interacts with JMJD8. Interacts
CC with TRAF4. Interacts with (phosphorylated) CTNNB1; leading to activate
CC transcription. {ECO:0000250|UniProtKB:P14618}.

CC -!- PTM: [Isoform M2]: Acetylated by EP300, leading to impair
CC phosphoenolpyruvate substrate-binding and promote its homodimerization
CC and subsequent translocation to the nucleus. Deacetylation by SIRT6
CC promotes its nuclear export into the cytoplasm, leading to suppress its
CC nuclear localization and oncogenic function.
CC {ECO:0000250|UniProtKB:P14618}.
CC -!- PTM: FGFR1-dependent tyrosine phosphorylation is reduced by interaction
CC with TRIM35. {ECO:0000250|UniProtKB:P14618}.
CC -!- MISCELLANEOUS: There are 4 isozymes of pyruvate kinase in mammals (L,
CC R, M1, M2) encoded by 2 different genes: PKLR and PKM. The L and R
CC isozymes are generated from the PKLR by differential splicing of RNA;
CC the M1 and M2 forms are produced from the PKM gene by differential
CC splicing. L type is major isozyme in the liver, R is found in red
CC cells, M1 is the main form in muscle, heart and brain, and M2 is found
CC in early fetal tissues as well as in most cancer cells.
CC {ECO:0000250|UniProtKB:P14618}.
CC -!- SIMILARITY: Belongs to the pyruvate kinase family. {ECO:0000305}.
