Gene: Mir320a (microRNA 320a) Rattus norvegicus
Symbol: Mir320a
Name: microRNA 320a
RGD ID: 2325539
Description: Predicted to enable mRNA base-pairing translational repressor activity. Involved in several processes, including cellular response to hypoxia; negative regulation of mitochondrial membrane potential; and response to ischemia. Predicted to be located in extracellular space. Predicted to be part of RISC complex. Orthologous to human MIR320A (microRNA 320a); INTERACTS WITH 1,3,5-trinitro-1,3,5-triazinane; 2,5-hexanedione; 2-methoxyethanol.
Type: ncrna (Ensembl: miRNA)
