What is the function of this protein?
Adipokine secreted by white adipose tissue that plays an important regulatory role in the glucose metabolism of liver, muscle and pancreas (PubMed:27087445, PubMed:30853600).  Hormone that targets the liver in response to fasting to increase plasma glucose levels (PubMed:27087445).  Binds the olfactory receptor OR4M1 at the surface of hepatocytes and promotes hepatocyte glucose release by activating the protein kinase A activity in the liver, resulting in rapid glucose release into the circulation (PubMed:27087445, PubMed:31230984).  May act as a regulator of adaptive thermogenesis by inhibiting browning and energy consumption, while increasing lipid deposition in white adipose tissue (By similarity).  Also acts as an orexigenic hormone that increases appetite: crosses the blood brain barrier and exerts effects on the hypothalamus (By similarity).  In the arcuate nucleus of the hypothalamus, asprosin directly activates orexigenic AgRP neurons and indirectly inhibits anorexigenic POMC neurons, resulting in appetite stimulation (By similarity).  Activates orexigenic AgRP neurons via binding to the olfactory receptor OR4M1 (By similarity).  May also play a role in sperm motility in testis via interaction with OR4M1 receptor (By similarity).
What are the official names of this protein?
Fibrillin-1.
What is the protein family that this protein belongs to?
Belongs to the fibrillin family.
What are the subcellular locations of this protein?
Secreted. Note=Fibrillin-1 and Asprosin chains are still linked together during the secretion from cells, but are subsequently separated by furin (PubMed:24982166). SUBCELLULAR LOCATION: [Fibrillin-1]: Secreted, extracellular space, extracellular matrix. SUBCELLULAR LOCATION: [Asprosin]: Secreted. Note=Secreted by white adipose tissue and circulates in the plasma.
