Gene: Mir20a (microRNA 20a) Rattus norvegicus
Symbol: Mir20a
Name: microRNA 20a
RGD ID: 2325401
Description: Predicted to enable mRNA 3'-UTR binding activity and mRNA base-pairing translational repressor activity. Predicted to be involved in several processes, including negative regulation of macromolecule biosynthetic process; regulation of angiogenesis; and regulation of signal transduction. Predicted to act upstream of or within several processes, including cellular response to forskolin; embryo implantation; and long-term synaptic potentiation. Predicted to be located in extracellular exosome. Predicted to be part of RISC complex. Biomarker of non-alcoholic fatty liver disease. Orthologous to human MIR20A (microRNA 20a); INTERACTS WITH 2,5-hexanedione; 2-acetamidofluorene; 2-methoxyethanol.
Type: ncrna (Ensembl: miRNA)
Previously known as: microRNA mir-20a; rno-mir-20a
