COX7C (Cytochrome C Oxidase Subunit 7C): COX7C is a gene that encodes a subunit of cytochrome c oxidase, a crucial enzyme complex found in the mitochondria. This complex plays a central role in the electron transport chain, an essential stage in cellular respiration. By facilitating the transfer of electrons and protons, COX7C helps drive the production of cellular energy in the form of adenosine triphosphate (ATP).
