Fusion Regulatory Protein 1, Heavy Chain

**Definition:** A transmembrane glycoprotein subunit that can dimerize with a variety of light chain subunits such as SLC7A5; SLC7A6, and 4F2 LIGHT CHAINS. This protein subunit serves a diverse array of functions including amino acid transport and cell fusion. Its function is altered depending which of the light chain subunits it interacts with.
