### MIR4457 Gene Overview

**Gene Symbol:** MIR4457  
**Type:** MicroRNA (miRNA)  
**Length:** 20-24 nt (nucleotides)

#### Function
MIR4457 is a microRNA gene that plays a critical role in the post-transcriptional regulation of gene expression in multicellular organisms. It modulates the stability and translation of target mRNAs through incorporation into the RNA-induced silencing complex (RISC), resulting in translational repression or degradation of the target transcripts.
