SHFL — Shiftless antiviral inhibitor of ribosomal frameshifting
SHFL belongs to a gene co-expression module in 4 of 28 SCUBA cell types. Each module groups genes that rise and fall together in that cell type; the genes it shares a module with are its closest co-expression partners there.

Function
Inhibits programmed -1 ribosomal frameshifting (-1PRF) of a variety of mRNAs from viruses, such as HIV1, and cellular genes, such as PEG10. Interacts with the -1PRF signal of target mRNA and translating ribosomes and causes premature translation termination at the frameshifting site. Regulates HIV1 GAG-POL expression by inhibiting -1PRF. Exhibits antiviral activity against dengue virus (DENV) and can inhibit the replication of all DENV serotypes. May block the protein translation of DENV RNA via its association with cellular mRNA-binding proteins and viral RNA. Also interrupts Zika virus replication by promoting viral NS3 degradation via a lysosome-dependent pathway. Can also limit the replication of hepatitis C virus (HCV) by restricting formation of viral replication organelle, West Nile virus (WNV), Chikungunya virus (CHIKV), herpes simplex virus type 1 (HHV-1), herpes virus type 8 (HHV- 8) and human adenovirus. Binds nucleic acids with a higher affinity for ssRNA and ssDNA than for dsDNA. Isoform 4 does not inhibit programmed ribosomal frameshifting (-1PRF). Does not bind to ribosomes
