fissignins
Fissignins are a class of small, secreted proteins that have been identified in certain species. Their precise biological function is still an active area of research, but they are thought to play roles in cell-cell interactions and potentially in developmental processes. Fissignins are characterized by a conserved amino acid sequence that suggests a common evolutionary origin. They are typically found in the extracellular space, implying they act by interacting with molecules on the cell surface or with other extracellular components.
Studies investigating fissignins have primarily focused on their presence and expression patterns in specific tissues and
