Activity summary

Apo-D also known as apolipoprotein D is a glycoprotein with an approximate mass of 29 kilodaltons. As an apolipoprotein Apo-D is part of the lipocalin family which participates in the transport of small hydrophobic molecules. It is widely expressed in human tissues particularly in the brain liver and adrenal glands. The expression of Apo-D in these tissues suggests important roles in diverse physiological processes and lipid metabolism. Scientists often study Apo-D to understand its involvement in lipid transport and its biological activities.

Biological function summary

Apo-D interacts with various molecules affecting lipid and cholesterol transport and metabolism. Apo-D operates as part of a protein complex and binds ligands such as progesterone and arachidonic acid. These interactions suggest it might modulate their availability and activity in biological systems. Furthermore the role of Apo-D in protecting cells against oxidative stress emerges as an important mechanism of action contributing to its protective properties in neural and other tissues.

Pathways

Apo-D plays significant roles by influencing the HDL (high-density lipoprotein) metabolism pathway and the arachidonic acid pathway. Within the HDL pathway Apo-D associates with other apolipoproteins like apoA-I to regulate cholesterol transport and anti-inflammatory responses. Its involvement in the arachidonic acid pathway suggests a possible regulatory effect on inflammation and cellular stress responses highlighting the complex interaction of Apo-D with other proteins like cyclooxygenases which are key players in inflammation.

Associated diseases and disorders

Researchers have linked Apo-D to conditions such as Alzheimer's disease and schizophrenia. In Alzheimer's disease its altered expression in the brain suggests a protective response or involvement in disease progression possibly through interaction with amyloid precursor proteins or influencing cholesterol metabolism. In schizophrenia abnormal levels of Apo-D in cerebrospinal fluid mark potential disturbance in lipid metabolism making it a protein of interest in the disease's complex pathophysiology. Understanding these connections provides insight into therapeutic strategies that target the biological functions of Apo-D.
