Fup2

Fup2, also known as Filamin A-binding protein 2, is a gene that encodes a protein of the same name. This protein is a member of the filamin family, which are actin-binding proteins involved in the structural integrity and organization of the cytoskeleton. Fup2 plays a role in various cellular processes, including cell adhesion, migration, and the regulation of cell shape. It interacts with a range of other proteins, contributing to the complex network that governs cellular mechanics and signaling.

The Fup2 protein is characterized by its large size and the presence of multiple actin-binding domains. These domains allow it to cross-link actin filaments, thereby influencing the mechanical properties of the cell. It is expressed in a variety of tissues, with particularly high levels found in muscle and brain. Dysregulation or mutations in the Fup2 gene have been linked to certain human diseases, suggesting its importance in maintaining normal physiological function. Research into Fup2 continues to explore its precise molecular mechanisms and its involvement in both normal development and disease pathogenesis.
