### Gene Overview: SLC66A1L

The **SLC66A1L** gene encodes a member of the solute carrier family, specifically believed to function as a transporter for amino acids such as **L-arginine** and **L-lysine**. This gene plays a crucial role in transmembrane transport processes and is speculated to be active in the lysosomal membrane, where it is predicted to function as an integral membrane protein.
