CC -!- FUNCTION: Plays an important role in the organization of the CC cytoskeleton. Binds to and sequesters actin monomers (G actin) and CC therefore inhibits actin polymerization (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- TISSUE SPECIFICITY: Ubiquitous. CC -!- SIMILARITY: Belongs to the thymosin beta family.
