Crebh(1-?) enters the nucleoplasm and induces the expression of APOA4, APOA5, APOC2, CIDEC and FGF21 (Lee et al. 2011). APOA4, APOA5 and APOC2 are known to augment lipoprotein lipase (LPL) activity. LPL is bound to the vascular endothelium, and hydrolyzes chylomicron and VLDL- associated TG to facilitate the transport of hydrolyzed fatty acids to peripheral cells. Patients with genetic defects in AOPC2, APOA5 or LPL display high circulating TG levels due to impaired TG clearance. Identification of APOA4, APOA5 and APOC2 as CREB-H target genes suggests that CREB-H might be involved in TG catabolism. CREB-H also strongly induces FGF21, a liver expressed hormone that has antidiabetic and TG- lowering effects, and CIDEC which encodes a lipid droplet-associated protein (Lee 2012).
