Redefining actin dynamics of the pointed-end complex in striated muscle

Trends Cell Biol. 2021 Sep;31(9):708-711. doi: 10.1016/j.tcb.2021.06.006. Epub 2021 Jul 12.

Abstract

Striated muscle is intricately designed to provide efficient and powerful muscle contractions. Recently, a long sought-after missing component of the thin filament pointed-end machinery was discovered: cyclase-associated protein 2 (CAP2). CAP2 was identified as a crucial contributor to actin polymerization, striated muscle development, and severe muscle disease when mutated.

Keywords: actin; muscle; myopathy; sarcomere; thin filament.
