Protein

Complement C1q-like protein 3

Gene
C1QL3, CTRP13
Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at transcript leveli

Functioni

May regulate the number of excitatory synapses that are formed on hippocampus neurons. Has no effect on inhibitory synapses By similarity. Plays a role in glucose homeostasis. Via AMPK signaling pathway, stimulates glucose uptake in adipocytes, myotubes and hepatocytes and enhances insulin-stimulated glucose uptake. In a hepatoma cell line, reduces the expression of gluconeogenic enzymes G6PC and PCK1 and hence decreases de novo glucose production By similarity.
