Chromosome 1 open reading frame 198 (C1orf198) is a protein that in humans is encoded by the C1orf198 gene. This particular gene does not have any paralogs in Homo sapiens, but many orthologs have been found throughout the Eukarya domain. C1orf198 has high levels of expression in all tissues throughout the human body, but is most highly expressed in lung, brain, and spinal cord tissues. Its function is most likely involved in lung development and hypoxia-associated events in the mitochondria, which are major consumers of oxygen in cells and are severely affected by decreases in available cellular oxygen.
