Regulation of the poly(A) tail is essential for selective protein translation in early embryos. However, the mechanisms that determine and maintain the length of maternal mRNA poly(A) tails remain ...

Ubiquitin is a small, covalent modifier that forms a poly-ubiquitin chain on protein, which becomes a degradation signal attacked by the 26S proteasome 11,12,13. The poly-ubiquitin chain is ...

Each bead can only have a single layer of protein or peptide on it ... to combine proteins and peptides with the polymer poly(N-isopropylacrylamide), or PNIPAM, in microparticles.
