RA   Fujiki K., Nakao M., Shin D., Yano T.;
RT   "Molecular cloning of carp (Cyprinus carpio) thymosin beta b.";
RL   Submitted (JUN-1999) to the EMBL/GenBank/DDBJ databases.
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). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the thymosin beta family. {ECO:0000305}.
