YTHDF1 (YT521-B homology domain-containing family protein 1) is a reader protein that specifically recognizes N6-methyladenosine (m6A), the most prevalent internal chemical modification in eukaryotic mRNA. Discovered as part of the dynamic m6A epitranscriptomic regulatory system, YTHDF1 binds m6A-modified transcripts through its conserved YTH domain, influencing mRNA stability, translation, and cellular localization. It plays a critical role in post-transcriptional gene regulation, particularly in promoting the translation of m6A-marked mRNAs by recruiting translation initiation factors and ribosomes.
Recombinant YTHDF1 proteins are engineered in vitro using expression systems (e.g., *E. coli* or mammalian cells) to study its molecular interactions and functional mechanisms. These proteins are often tagged with affinity markers (e.g., His-tag, GST) for purification and experimental detection. Researchers employ recombinant YTHDF1 to investigate m6A-dependent regulatory pathways, including neurodevelopment, immune responses, and cancer progression, where dysregulated m6A methylation is linked to disease states. For example, YTHDF1 overexpression in tumors has been associated with enhanced oncogene translation and poor prognosis.
Studies using recombinant YTHDF1 also explore its structural biology, such as binding specificity to m6A motifs, and its crosstalk with other epitranscriptomic components (writers like METTL3 and erasers like FTO). Additionally, it serves as a tool for developing m6A detection assays or screening small molecules targeting m6A-related pathologies. The production of high-purity, bioactive YTHDF1 recombinant protein remains essential for advancing both basic research and therapeutic discovery in the rapidly growing field of epitranscriptomics.
