Anticipating mechanisms of resistance to PI3K inhibition in breast cancer: a challenge in the era of precision medicine.

abstract：:Tandem repeats (TR) in proteins are common in nature and have several unique functions. They come in various forms that are frequently difficult to recognize from a sequence. A previously proposed structural classification has been recently implemented in the RepeatsDB database. This defines five main classes, mainly ...
