蛋白磷酸酶2A （PP2A）是一种重要的蛋白丝氨酸/苏氨酸磷酸酶，在所有的真核细胞中结构保守。

Protein phosphatase type 2A (PP2A) is an essential protein serine/threonine phosphatase that is conserved in all eukaryotes.

目标蛋白特定序列和基序的可逆丝氨酸和苏氨酸残基磷酸化是信号转导通路的标志。

A hallmark of signal transduction pathways is the reversible phosphorylation of serine and threonine residues within specific sequences, or motifs, in target proteins.

此抗体与包含-5、-3位上是精氨酸的磷酸化丝氨酸/苏氨酸的肽段有偏好的交叉反应。

There is some preference observed for peptides that contain phospho-serine/threonine preceded by arginine at both positions -5 and -3. (U.
