RO60
Domain
The horseshoe-shaped TROVE domain is built with 7 helical HEAT-like repeats, and is closed by the VWFA-like domain giving rise to a ring-shaped monomer. Single-stranded RNA is bound in the positively charged central cavity (By similarity).
The MIDAS-like motif in the VWFA-like domain binds divalent metal cations.
Function
RNA-binding protein that binds to misfolded non-coding RNAs, pre-5S rRNA, and several small cytoplasmic RNA molecules known as Y RNAs (PubMed:18056422, PubMed:26382853). Binds to endogenous Alu retroelements which are induced by type I interferon and stimulate porinflammatory cytokine secretion (PubMed:26382853). Regulates the expression of Alu retroelements as well as inflammatory genes (PubMed:26382853). May play roles in cilia formation and/or maintenance (By similarity).
Sequence Similarities
Belongs to the Ro 60 kDa family.
Cellular localization
- Cytoplasm
- Localized in cytoplasmic mRNP granules containing untranslated mRNAs.
