**提示**：
- 实际文献需通过 **PubMed/Google Scholar** 以关键词 "PHTF1"、"recombinant PHTF1 protein" 等检索;
- PHTF1研究可能多集中于其基因功能(如肿瘤发生、表观调控)，直接针对重组蛋白的研究可能较少，可扩展至相关通路。
**Recombinant Human PHTF1 Protein: Background**
PHTF1 (Putative Homeodomain Transcription Factor 1), also known as PHF1 (PHD Finger Protein 1), is a protein encoded by the *PHTF1* gene in humans. It belongs to the PHD finger protein family, characterized by a conserved plant homeodomain (PHD) zinc finger motif, which often mediates interactions with modified histone tails or other chromatin-associated proteins. PHTF1 is implicated in transcriptional regulation, epigenetic modifications, and cellular processes such as DNA repair, cell cycle control, and apoptosis. Its role in tumorigenesis remains debated, with studies suggesting both tumor-suppressive and oncogenic functions depending on cellular context.
Recombinant human PHTF1 protein is produced using biotechnological methods, typically via heterologous expression in *E. coli* or mammalian cell systems, followed by purification (e.g., affinity tags like His-tag). This engineered protein retains functional domains, enabling studies on its biochemical properties, interaction partners (e.g., histones, chromatin remodelers), and mechanisms in DNA damage response or gene silencing. Researchers utilize recombinant PHTF1 to investigate its involvement in cancers, neurological disorders, and developmental pathways. It also serves as a tool for drug screening, particularly targeting epigenetic therapies. Despite limited understanding of its full biological spectrum, PHTF1 represents a promising target for exploring chromatin dynamics and disease therapeutics.
