Protein

Thymosin beta-4

Gene

Tmsb4x

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Plays an important role in the organization of the cytoskeleton. Binds to and sequesters actin monomers (G actin) and therefore inhibits actin polymerization.
Seraspenide inhibits the entry of hematopoietic pluripotent stem cells into the S-phase.By similarity
