Prominin
The prominins are an emerging family of proteins that among the multispan membrane proteins display a novel topology. Mouse prominin and human prominin (mouse)-like 1 (PROML1) are predicted to contain five membrane spanning domains, with an N-terminal domain exposed to the extracellular space followed by four, alternating small cytoplasmic and large extracellular, loops and a cytoplasmic C-terminal domain. The exact function of prominin is unknown although in humans defects in PROM1, the gene coding for prominin, cause retinal degeneration.
