**Background of RTL1 Recombinant Protein**
RTL1 (Retrotransposon Gag-like 1), also known as **PEG11** (Paternally Expressed Gene 11), is a maternally imprinted gene located within the **DLK1-DIO3 genomic region** on human chromosome 14 (14q32.2). This gene plays a critical role in placental and embryonic development, particularly in mammals. RTL1 encodes a protein with structural similarities to retroviral Gag proteins, featuring domains associated with nucleic acid binding and protein multimerization. Its expression is tightly regulated through genomic imprinting, where only the paternal allele is actively transcribed. Dysregulation of RTL1 has been linked to developmental disorders, including **Kagami-Ogata syndrome** and **Silver-Russell syndrome**, highlighting its importance in growth and cellular differentiation.
Recombinant RTL1 protein is produced using biotechnological systems (e.g., *E. coli*, mammalian cells*) to enable functional studies. The protein is purified via affinity tags (e.g., His-tag) and validated for activity through assays like Western blotting or ELISA. Researchers utilize recombinant RTL1 to investigate its roles in **cell proliferation**, **apoptosis regulation**, and **viral defense mechanisms**, as well as its interactions with RNA and other cellular components. Additionally, it serves as a tool for exploring imprinting disorders and developing therapeutic strategies for related pathologies.
Studies in model organisms, such as mice, have shown that RTL1 deficiency leads to placental vascularization defects and embryonic lethality, underscoring its conserved biological significance. The recombinant protein thus bridges molecular insights with potential clinical applications in developmental biology and regenerative medicine.
