APOC2

Apolipoprotein C2 or Apolipoprotein C-II is a protein that in humans is encoded by the APOC2 gene. The protein encoded by this gene is secreted in plasma where it is a component of very low density lipoproteins and chylomicrons. This protein activates...

Disease relevance of Apoc2

Furthermore, the decrease of LPL activity in the heart, along with the inhibitory effects of excess APOC2, may contribute to the hypertriglyceridemia observed in apoC-II transgenic mice. Finally, we demonstrate that apolipoprotein C-II in human atheroma...

Mechanism of action of BDNF

BDNF binds at least two receptors on the surface of cells that are capable of responding to this growth factor, TrkB (pronounced "Track B") and the LNGFR (for low-affinity nerve growth factor receptor, also known as p75). It may also modulate the activity...

Secretion of BDNF

BDNF is made in the endoplasmic reticulum and secreted from dense-core vesicles. It binds carboxypeptidase E (CPE), and the disruption of this binding has been proposed to cause the loss of sorting of BDNF into dense-core vesicles. The phenotype for BDNF...

Receptor of BDNF

The other BDNF receptor, the p75, plays a somewhat less clear role. Some researchers have shown that the p75NTR binds and serves as a "sink" for neurotrophins. Cells that express both the p75NTR and the Trk receptors might, therefore, have a greater activity,...
