**Recombinant human HP1BP3 (Heterochromatin Protein 1 Binding Protein 3)** is a chromatin-associated protein involved in epigenetic regulation and nuclear organization. HP1BP3. also known as NKAPD1. belongs to the HP1-binding protein family and interacts with heterochromatin protein 1 (HP1), a key player in heterochromatin formation and gene silencing. Structurally, it contains conserved domains for chromatin binding, nuclear localization, and interaction with HP1. Its role spans chromatin compaction, transcriptional regulation, and maintaining genomic stability, particularly during the cell cycle and DNA repair.
Recombinant HP1BP3 is produced using expression systems like *E. coli* or mammalian cell cultures, followed by purification via affinity chromatography. This engineered protein enables functional studies to dissect its involvement in chromatin dynamics, cellular differentiation, and epigenetic inheritance. Research highlights its potential relevance in cancer biology, as aberrant HP1BP3 expression correlates with tumor progression and therapeutic resistance. Additionally, it serves as a tool for exploring chromatin-related diseases and screening epigenetic drug candidates. Further studies aim to clarify its precise molecular mechanisms and therapeutic applications in human health.
