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.^[5]^[6]

Function and structure

STARD13 serves as a Rho GTPase-activating protein (GAP), a type of protein that regulates members of the Rho family of GTPases.^[7] It selectively activates RhoA and CDC42 and suppresses cell growth by inhibiting actin stress fiber assembly.^[7]

The protein consists of an N-terminal sterile alpha motif (SAM) domain,^[8] a serine-rich domain, a RhoGAP domain and at the C-terminus, a StAR-related lipid-transfer domain (START).

Tissue distribution and pathology

The protein was identified in part through its differential expression in cancers. A low level of STARD13 was observed in less differentiated hepatocellular carcinoma tissue with higher RhoA expression. A small patient study finds that the absence of STARD13 in hepatocellular carcinomas correlates with higher levels of RhoA and a poorer prognosis than patients with carcinomas that were STARD13-positive.^[9]
