Zinc finger CCCH domain-containing protein 11A is a protein that in humans is encoded by the ZC3H11A gene. [4] [5] ZC3H11A is a part of the transcription export (TREX) complex and plays a role in exporting of mRNAs from nucleus to cytoplasm. [6] It is considered as stress-induced nuclear protein and maintains mRNAs exporting when the cells are under stress. [7] Loss of functioning of ZC3H11A gene in HeLa cells results in abortion of the replication of nuclear replicating viruses but not cytoplasmic replicating viruses. [8] It is discovered that ZC3H11A is significant for viability and metabolic regulation of mouse embryo [9]
