TYW3 is a human protein encoded by the TYW3 gene, playing a critical role in tRNA modification as part of the Trm5 family. It functions in the biosynthesis of wybutosine (yW), a hypermodified nucleoside found at position 37 of eukaryotic tRNAPhe. This modification stabilizes tRNA structure, enhances translational fidelity, and prevents ribosomal frameshifting. TYW3 operates in a multi-enzyme complex with TYW1 and TYW2. catalyzing methyl group transfer using S-adenosylmethionine (SAM) as a cofactor. Its activity is vital for maintaining protein synthesis accuracy and cellular homeostasis.
Structurally, TYW3 contains conserved methyltransferase domains and cofactor-binding motifs. Dysregulation of TYW3 has been linked to diseases, including colorectal cancer, where its overexpression is associated with tumor progression, and neurodevelopmental disorders, possibly due to impaired tRNA modification affecting neural gene expression. Recent studies explore its potential as a therapeutic target, particularly in cancers reliant on heightened translation. Research also investigates its role in mitochondrial function and neurodegenerative diseases, highlighting its broader impact on cellular metabolism and stress responses. TYW3 exemplifies the functional significance of epitranscriptomic modifications in health and disease. (Word count: 198)
