Proteins can be secreted, or transferred out of a cell, by multiple pathways. Constitutive secretion is one of these processes. In constitutive secretion proteins are secreted from a cell continuously, regardless of external factors or signals. This pathway is also used by all eukaryotic cells to maintain the cell's plasma membrane.
