ApoptoticDNAfragmentationandtissuehomeostasis
Apoptotic cell death can be triggered by many different cellular stimuli, resulting in activation of apoptotic signaling pathways including caspases (see Caspase Cascade pathway) and mitochondria (see Role of Mitochondria in Apoptotic Signaling pathway). A cellular response that is characteristic of apoptosis is fragmentation of the nuclear genome to create a nucleosomal ladder. This activity is conducted by multiple......阅读全文

ACIN1基因编码功能及结构描述
细胞凋亡是由核的形态变化所决定的，包括染色质浓缩和核碎裂。该基因编码一种核蛋白，在caspase-3激活后诱导凋亡染色质浓缩，而不诱导dna断裂。该蛋白还被证明是一种剪接依赖性多蛋白外显子连接复合体（EJC）的组成部分，其在mRNAs的剪接连接处沉积，是mRNA前剪接的结果因此，它可能参与与剪接相关
