  Function in Host
Transcription factor that binds to cytidine clusters indouble-stranded DNA. Plays a key rolein the silencing of unintegrated retroviral DNA: some part of theretroviral DNA formed immediately after infection remains unintegratedin the host genome and is transcriptionally repressed. Mediates transcriptional repression of unintegratedviral DNA by specifically binding to the cytidine clusters ofretroviral DNA and mediating the recruitment of chromatin silencers, such as the HUSH complex, SETDB1 and the histone deacetylases HDAC1 andHDAC4. Acts as an early regulator of adipogenesis byacting as a transcription cofactor of CEBPs (CEBPA, CEBPD and/orCEBPG), controlling the expression of PPARG and probably of otherproadipogenic genes, such as SREBF1. May also regulatealternative splicing of target genes during adipogenesis. [1-2]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Pro-viral [3]
Infected TissueLung Infection Time7-9 Days
Infected CellCalu-3 Cells (Human epithelial cell line) Cellosaurus IDCVCL_0609 
Method DescriptionTo detect the role of host protein ZNF638 in viral infection, ZNF638 protein knockout Calu-3 Cells were infected with SARS-COV-2 for 7 - 9 Days , and the effects on infection was detected through CRISPR-based genome-wide gene-knockout screen.
ResultsIt is reported that knockout of ZNF638 leads to the decreased SARS-CoV-2 RNA levels compared with control group.
