| Modification Notes |
Members of the rhomboid family of integral membrane proteins are related to Drosophila Rhomboid-1, a serine protease that cleaves the membrane domain of the Drosophila EGF-family protein, Spitz, to release a soluble growth factor. Rhomboid veinlet-like protein 6 (RHBDL6) is a 856 amino acid multi-pass endoplasmic reticulum membrane protein belonging to the rhomboid family. As an intramembrane protein, RHBDL6 has no protease activity but regulates the secretion of several ligands of the epidermal growth factor receptor. RHBDL6 may also indirectly activate the epidermal growth factor receptor signaling pathway and may thereby regulate sleep, cell survival, proliferation and migration. RHBDL6 can exist as two isoforms due to alternative splicing events. RHBDL6 is encoded by a gene mapping to human chromosome 17p25.1. |
