FAM214B

The FAM214B, also known as protein family with sequence similarity 214, B (FAM214B) is a protein that, in humans, is encoded by the FAM214B gene located on the human chromosome 9.[5] The protein has 538 amino acids.[6] The gene contain 9 exon.[6] There has been studies that there are low expression of this gene in patients with major depression disorder.[7][8] In most organisms such as mammals, amphibians, reptiles, and birds, there are high levels of gene expression in the bone marrow and blood.[9] For humans in fetal development, FAM214B is mostly expressed in the brains and bone marrow.[9]

Evolutionary history

FAM214B Evolution Trend

The most distant species relating to humans was Mikania micrantha which was about 1496 MYA. The most closely related relative for this gene found in mammals comparing to humans was the mouse which was dated about 90 MYA.[33] The FAM214B is conserved in Eukaryota. In terms of the molecular clock analysis, it seems that FAM214B has evolved quicker than Cytochrome c but much slower than Fibrinogen alpha.

Studies of clinical significance

There are studies that show the gene expression of KIAA1539 in patients with major depression disorders by using biomarkers to detect vulnerability to recurrent depression.[8] Low expression of this gene was common in patients who have MDD and was significantly difference than those who did not have MDD.[7][8] Experiments were conducted in patients with major depression disorders by using biomarkers to detect vulnerability to recurrent depression and is expressed in patients with depressive disorders before and after cognitive behavioral therapy.[34]
