TMCC1
Chr 3transmembrane and coiled-coil domain family 1
Enables identical protein binding activity. Involved in several processes, including endosome fission; endosome membrane tubulation; and membrane fission. Located in cytosol; endoplasmic reticulum-endosome membrane contact site; and rough endoplasmic reticulum. [provided by Alliance of Genome Resources, Jul 2025]
