SND1
Function
Endonuclease that mediates miRNA decay of both protein-free and AGO2-loaded miRNAs (PubMed:18453631, PubMed:28546213). As part of its function in miRNA decay, regulates mRNAs involved in G1-to-S phase transition (PubMed:28546213). Functions as a bridging factor between STAT6 and the basal transcription factor (PubMed:12234934). Plays a role in PIM1 regulation of MYB activity (PubMed:9809063). Functions as a transcriptional coactivator for STAT5 (By similarity).
(Microbial infection) Functions as a transcriptional coactivator for the Epstein-Barr virus nuclear antigen 2 (EBNA2).
(Microbial infection) Promotes SARS-CoV-2 RNA synthesis by binding to negative-sense RNA and the viral protein nsp9.
Post-translational modifications
Phosphorylated by PIM1 in vitro.
Tissue Specificity
Ubiquitously expressed.
Cellular localization
- Cytoplasm
- Nucleus
- Melanosome
- In IL-4 stimulated cells colocalizes with STAT6 in the nucleus (PubMed:12234934). Identified by mass spectrometry in melanosome fractions from stage I to stage IV (PubMed:17081065).
