During development, neurons form growth cones and neurites, but later reduce these activities to maintain a stable architecture. In this issue of Developmental Cell, LaBella et al. demonstrate that CK1δ plays a key role in winding down developmental processes exclusively by regulating poly(A) site choice to promote giant Ankyrin isoform expression.

酪蛋白激酶1δ触发巨锚蛋白表达。

在发育过程中，神经元形成生长锥和神经突，但后来减少了这些活动以维持稳定的结构。在本期《发育细胞》中，LaBella等人。证明CK1δ通过调节poly（A）位点选择以促进巨锚蛋白同工型表达，在终止发育过程中起关键作用。
