### Overview of the MIR378G Gene

**Gene Symbol:** MIR378G  
**Function:** MIR378G encodes a microRNA, which is a class of short (20-24 nucleotides) non-coding RNAs that play critical roles in the post-transcriptional regulation of gene expression. MicroRNAs are transcribed as part of larger primary transcripts and are subsequently processed into mature miRNAs that participate in gene silencing by binding to complementary sequences in target mRNAs.
