Abstract
Formative cell divisions generate new cell types and tissues during development, and are controlled by receptor kinase signalling pathways. The phosphatase PP2A has now been shown to be both a target and positive regulator of the receptor kinase ACR4, thus creating a feed-forward loop that serves to establish new cell fates.
摘要
有丝分裂产生新的细胞类型和组织在发展过程中，并受受体激酶信号通路的控制。现在已经表明，磷酸酶 PP2A 既是受体激酶 ACR4 的靶标又是其正调节剂，从而形成正向反馈环，有助于建立新的细胞命运。
