CYCS may refer to:
- Cytochrome c, a protein
- Cyclorama (theater) plural - a large curtain or wall, often concave, positioned at the back of the stage area
- the ICAO code for Chesterfield Inlet Airport in Nunavut, Canada
The cytochrome complex, or cyt c is a small hemeprotein found loosely associated with the inner membrane of the mitochondrion. It belongs to the cytochrome c family of proteins. Cytochrome c is highly water-soluble, unlike other cytochromes, and is an essential component of the electron transport chain, where it carries one electron. It is capable of undergoing oxidation and reduction, but does not bind oxygen. It transfers electrons between Complexes III and IV. In humans, cytochrome c is encoded by the CYCS gene.
A cyclorama is a large curtain or wall, often concave, positioned at the back of the apse. It was popularized in the German theater of the 19th century and continues in common usage today in theaters throughout the world. A "cyc" can be made of unbleached canvas or muslin, filled scrim, or seamless translucent plastic. Traditionally it is hung at 0% fullness (flat). When possible, it is stretched on the sides and weighted on the bottom to create a flat and even surface. As seams tend to interrupt the smooth surface of the cyclorama, it is usually constructed from extra-wide material.
Chesterfield Inlet Airport is located 1 nautical mile northwest of Chesterfield Inlet, Nunavut, Canada, and is operated by the government of Nunavut.
