Definition: In biology, actinomeric proteins are proteins that have a conformational structure which enables them to bind with other proteins. They are typically found in organelles such as mitochondria or chloroplasts where they play a critical role in energy production and oxidative phosphorylation. The term "actinomeric" is derived from the word "actin," which is the primary filament that runs along the cell membrane of a cell, and the word "omer", which refers to an organic molecule. In simpler terms, actinomeric proteins are like small pieces of glue that hold together other proteins in their environment. They do not form new structures but can help proteins bind with each other. For example, when cells divide or undergo mitosis (a process of cell division), they need to release their organelles into the cytoplasm for growth and division. In order to do this, the actinomeric protein filaments must be released from these organelles so that they can interact with other proteins. So in summary, "actinomeric" means having a conformational structure which enables proteins to bind together or interact with each other.
