StAR-related lipid transfer domain protein 13 (STARD13) also known as deleted in liver cancer 2 protein (DLC-2) is a protein that in humans is encoded by the STARD13 gene and a member of the DLC family of proteins.
STARD13 serves as a Rho GTPase-activating protein (GAP), a type of protein that regulates members of the Rho family of GTPases. It selectively activates RhoA and CDC42 and suppresses cell growth by inhibiting actin stress fiber assembly.
