Recombinant human RFT1 (RHFT1) protein is a biologically engineered variant of the RFT1 (Resistance to Fungicide Target 1 homolog) protein, which plays a critical role in the N-linked glycosylation pathway. In humans, RFT1 is an endoplasmic reticulum (ER)-resident transmembrane protein that facilitates the translocation of lipid-linked oligosaccharides (LLOs) across the ER membrane, a key step in the synthesis of glycoproteins. This process ensures proper protein folding, quality control, and cellular secretion. Mutations in the RFT1 gene are linked to congenital disorders of glycosylation (CDGs), notably RFT1-CDG, characterized by neurological impairments, developmental delays, and multi-systemic abnormalities.
The recombinant form is typically produced using heterologous expression systems, such as mammalian cell lines (e.g., HEK293 or CHO cells) or yeast, to enable high-yield, post-translationally modified protein production. Purification techniques like affinity chromatography ensure high purity for research applications. Recombinant RFT1 serves as a vital tool for studying glycosylation mechanisms, disease modeling, and drug screening. Its structural and functional analysis aids in elucidating molecular interactions within the glycosyltransferase complex, potentially guiding therapeutic strategies for CDGs. Current research also explores its role in cancer and immune regulation, where altered glycosylation patterns influence disease progression. Overall, recombinant RFT1 bridges biochemical insights with clinical applications in rare genetic disorders.
