### FAM86B1 Gene

**Gene Overview:**
The FAM86B1 (Family with Sequence Similarity 86 Member B1) gene is part of the class I-like SAM-binding methyltransferase superfamily, specifically categorized within the EEF2KMT family. Its predicted functionality involves methyltransferase activity, suggesting a role in the methylation of specific substrates, which is a crucial post-translational modification that can affect gene expression, protein function, and cellular signaling pathways.
