Profilin is a key protein regulating actin cytoskeleton dynamics in eukaryotic cells. This review covers profilin

Area of Science:

  • Cell Biology
  • Biochemistry

Context:

  • The actin cytoskeleton is crucial for cellular structure and function, undergoing dynamic rearrangements.
  • Actin-binding proteins, like profilin, regulate the polymerization and depolymerization of actin filaments.

Purpose:

  • To review the multifaceted roles of profilin in regulating actin cytoskeleton dynamics.
  • To explore profilin's biochemical properties, cellular distribution, and involvement in signal transduction pathways.
  • To highlight recent advancements in understanding profilin's function, particularly in plant cells.

Summary:

  • Profilin, a ubiquitous actin-monomer-binding protein, influences actin polymerization both positively and negatively.
  • It interacts with phosphatidylinositol 4,5-bisphosphate and poly-L-proline, suggesting diverse functional roles.
