A 35-kbp region of genomic DNA encoding the human muscle phosphofructokinase (HPFK-M) gene including all of the coding exons (1-22) plus 2.2-kbp of 5'-flanking sequence has been cloned. The exon boundaries are the same as has been observed for the rabbit muscle phosphofructokinase (RPFK-M), the human liver phosphofructokinase (HPFK-L), and the mouse liver phosphofructokinase (MPFK-L) genes. Characterization of the structure of the HPFK-M gene and its transcript in Epstein-Barr virus transformed B-cell lines derived from patients with glycogen storage disease type VII (GSDVII or Tarui's disease) demonstrated that this single-copy gene encodes a normal sized 3.0-kb transcript in the four cases examined. This suggests the lesion in these cases represents either a point mutation or possibly a small insertion or deletion resulting in the synthesis of a defective HPFK-M protein. Analysis of the 5'-flanking region demonstrated the presence of a functional promoter located within 114 nucleotides of a proposed transcription initiation site. This promoter was active in the human cervical carcinoma cell line, HeLa S3, the dedifferentiated human hepatoma cell line, HepG2.1, and the mouse myoblast cell line, C2C12, suggesting this promoter has a broad cell-type specificity. In addition, from the known HPFK-M cDNA sequences, this observation indicates that the HPFK-M gene has a second promoter located upstream from the genomic region isolated in this study.

UI MeSH Term Description Entries
D007438 Introns Sequences of DNA in the genes that are located between the EXONS. They are transcribed along with the exons but are removed from the primary gene transcript by RNA SPLICING to leave mature RNA. Some introns code for separate genes.

D010732 Phosphofructokinase-1 An allosteric enzyme that regulates glycolysis by catalyzing the transfer of a phosphate group from ATP to fructose-6-phosphate to yield fructose-1,6-bisphosphate. D-tagatose- 6-phosphate and sedoheptulose-7-phosphate also are acceptors. UTP, CTP, and ITP also are donors. In human phosphofructokinase-1, three types of subunits have been identified. They are PHOSPHOFRUCTOKINASE-1, MUSCLE TYPE; PHOSPHOFRUCTOKINASE-1, LIVER TYPE; and PHOSPHOFRUCTOKINASE-1, TYPE C; found in platelets, brain, and other tissues. 6-Phosphofructokinase,6-Phosphofructo-1-kinase,Fructose-6-P 1-Kinase,Fructose-6-phosphate 1-Phosphotransferase,6 Phosphofructokinase,Phosphofructokinase 1

D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
