PEST sequence
PEST sequences are parts of proteins that are particularly rich in the amino acids proline ( P ), glutamate ( E ), serine ( S ) and threonine ( T ), which leads to a shorter half-life t 1/2 of the entire protein and thus to a faster breakdown in the proteasome . They are contained in androgen , estrogen and vitamin D receptors , among other things . The activity of PEST sequences is regulated by phosphorylation of neighboring domains .
