They are usually C-terminal signals, and a common mammalian one consists of the amino acids lysine, aspartate, gluatamate, and leucine, or KDEL. hnRNP C proteins contain one of them that allows them to override nuclear export signals. For 10 points, name these signals important in directing proteins to the correct membranes, most often used to prevent a protein's export from the endoplasmic reticulum.
