| Name | pyruvate carboxylase |
| Description | This gene encodes pyruvate carboxylase, which requires biotin and ATP to catalyse the carboxylation of pyruvate to oxaloacetate. The active enzyme is a homotetramer arranged in a tetrahedron which is located exclusively in the mitochondrial matrix. Pyruvate carboxylase is involved in gluconeogenesis, lipogenesis, insulin secretion and synthesis of the neurotransmitter glutamate. Mutations in this gene have been associated with pyruvate carboxylase deficiency. Alternatively spliced transcript variants with different 5' UTRs, but encoding the same protein, have been found for this gene. [provided by RefSeq, Jul 2008] |

{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\nPyruvate carboxylase (PC) is a biotin‐dependent mitochondrial enzyme that catalyzes the ATP‐driven conversion of pyruvate to oxaloacetate—a reaction central to anaplerosis, gluconeogenesis, lipogenesis, and the maintenance of the tricarboxylic acid (TCA) cycle. Structural investigations have detailed its complex multi‐domain organization (including the biotin carboxylase, carboxyltransferase, tetramerization, and biotin–carboxyl carrier protein domains), providing insights into its catalytic mechanism and the importance of oligomerization for full enzymatic activity. Tissue–specific regulation—illustrated by alternative promoter usage in pancreatic β–cells, its abundant presence in skeletal muscle, and its emerging role in supporting ATP‐linked respiration in brown adipocytes—underscores PC’s critical role in normal cellular metabolism."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "1", "end_ref": "8"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nIn the context of cancer biology, enhanced PC activity has been repeatedly implicated as a key metabolic adaptation to support rapid cell proliferation and metastasis.

In addition, PC overexpression in colorectal, ovarian, gastric, and prostate tumors—as well as in certain brain tumors such as astrocytomas and glioblastomas—has been linked to tumor progression via modulation of the extracellular matrix (for example, by supporting collagen production in tumor–associated fibroblasts) and by adapting to unique microenvironmental conditions."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "9", "end_ref": "18"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nMutations in the PC gene result in a spectrum of inherited metabolic disorders—ranging from neonatal lethal lactic acidosis to more chronic, milder presentations marked by developmental delay—highlighting its essential role in metabolic homeostasis.
