CUGBP (CUG-binding protein)

CUGBP (CUG-binding protein) is a type of protein that interacts specifically with RNA molecules containing CUG nucleotide sequences. It plays a significant role in controlling how genes are expressed by influencing the stability, localization, and translation of these RNA molecules. By binding to RNA, CUGBP helps regulate processes like cell growth and development. Its activity is important in normal biology but can also be involved in certain diseases, such as myotonic dystrophy, when it functions abnormally. Overall, CUGBP is a crucial regulator of gene expression at the post-transcriptional level.
