CTRP13 (C1qTNF-related protein 13) belongs to a highly conserved family of adiponectin paralogs. CTRP13 is an adipokine that promotes glucose uptake in adipocytes, myotubes and hepatocytes via activation of the AMPK signaling pathway. CTRP13 ameliorates lipid-induced insulin resistance in hepatocytes through suppression of the SAPK/JNK stress signaling that impairs the insulin signaling pathway. CTRP13 reduces glucose output in hepatocytes by inhibiting the mRNA expression of gluconeogenic enzymes, glucose-6-phosphatase and the cytosolic form of phosphoenolpyruvate carboxykinase. CTRP13 has insulin-sensitizing activity and is important in glucose homeostasis. CTRP13 is preferentially expressed by adipose tissue and the brain in mice and predominantly by adipose tissue in humans.

The globular domain of human CTRP13 (aa 120-255) is fused at the C-terminus to a His-tag.
