Protein
Protein phosphatase 2A catalytic subunit B
Organism
Dictyostelium discoideum
Function
Component of the Sca1 complex, a regulator of cell motility, chemotaxis and signal relay (PubMed:20493808). The Sca1 complex is recruited to the plasma membrane in a chemoattractant- and F-actin-dependent manner and is enriched at the leading edge of chemotaxing cells where it regulates F-actin dynamics and signal relay by controlling the activation of rasC and the downstream target of rapamycin complex 2 (TORC2)-Akt/protein kinase B (PKB) pathway (PubMed:20493808).
Similarity
Belongs to the PPP phosphatase family. PP-2A subfamily.
