PABP, or poly(A)-binding protein, is a key protein involved in the regulation of mRNA stability and translation in eukaryotic cells. It binds to the poly(A) tail of mRNA molecules, playing a crucial role in post-transcriptional gene regulation by influencing mRNA metabolism, transport, and translation efficiency. By interacting with other proteins and components of the translation machinery, PABP helps ensure that mRNAs are properly processed and translated into functional proteins.
congrats on reading the definition of PABP. now let's actually learn it.
