TRIM22 — Tripartite motif containing 22
TRIM22 belongs to a gene co-expression module in 10 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
Interferon-induced E3 ubiquitin ligase that plays important roles in innate and adaptive immunity. Restricts the replication of many viruses including HIV-1, encephalomyocarditis virus (EMCV), hepatitis B virus (HBV), hepatitis C virus (HCV) or Zika virus (ZIKV). Mechanistically, negatively regulates HCV replication by promoting ubiquitination and subsequent degradation of viral NS5A. Also acts by promoting the degradation of Zika virus NS1 and NS3 proteins through proteasomal degradation. Acts as a suppressor of basal HIV-1 LTR- driven transcription by preventing Sp1 binding to the HIV-1 promoter. Also plays a role in antiviral immunity by co- regulating together with NT5C2 the RIGI/NF-kappa-B pathway by promoting 'Lys-63'-linked ubiquitination of RIGI, while NT5C2 is responsible for 'Lys-48'-linked ubiquitination of RIGI. Participates in adaptive immunity by suppressing the amount of MHC class II protein in a negative feedback manner in order to limit the extent of MHC class II induction.
