背景信息

**Background of PGK2 Recombinant Protein**

Phosphoglycerate kinase 2 (PGK2) is an isoform of the phosphoglycerate kinase enzyme family, primarily involved in glycolysis and energy metabolism. Unlike its ubiquitously expressed counterpart, PGK1. PGK2 is encoded by a retrotransposed gene derived from PGK1 and is specifically expressed in germline cells, particularly during spermatogenesis in mammals. This tissue-specific expression is evolutionarily conserved, reflecting its critical role in male reproductive biology. PGK2 compensates for the transcriptional silencing of PGK1 in late-stage spermatogenic cells, ensuring continued glycolytic ATP production essential for sperm motility and maturation.

Structurally, PGK2 retains the conserved catalytic domains of PGK1 but lacks a functional N-terminal nucleotide-binding site due to evolutionary mutations. Recombinant PGK2 protein is typically produced using expression systems like *E. coli* or mammalian cells, enabling studies on its enzymatic activity, structure-function relationships, and interactions. Research highlights its dual role beyond glycolysis, including involvement in chromatin condensation during spermiogenesis and potential regulatory functions in oxidative stress responses.

PGK2 has garnered interest in reproductive health, cancer biology, and metabolic disorders. Aberrant PGK2 expression has been linked to male infertility, while its ectopic activation in certain cancers suggests a metabolic adaptation for tumor proliferation. Recombinant PGK2 serves as a tool for developing diagnostic assays, exploring infertility mechanisms, and designing targeted therapies. Its study bridges gaps in understanding metabolic plasticity in specialized cells and diseases.

In summary, PGK2 recombinant protein provides insights into cell-specific energy regulation, reproductive biology, and pathological pathways, underscoring its biomedical relevance.
