Physiology
The gene for MOG, found on chromosome 6p21.3-p22, was first sequenced in 1995. It is a transmembrane protein expressed on the surface of oligodendrocyte cell and on the outermost surface of myelin sheaths. “MOG is a quantitatively minor type I transmembrane protein, and is found exclusively in the CNS. “A single Ig-domain is exposed to the extracellular space" and consequently allows autoantibodies easy access. and therefore easily accessible for autoantibodies. The MOG “primary nuclear transcript … is 15,561 nucleotides in length" and, for humans, it has eight exons which are “separated by seven introns". The introns "contain numerous reptitive DNA" sequences, among which is "14 Alu sequences within 3 introns", and have a range varying from 242 to 6484 bp.

Famous quotes containing the word physiology:
“Now the twitching stops. Now you are still. We are through with physiology and theology, physics begins.”
—Alfred Döblin (1878–1957)
“The world moves, but we seem to move with it. When I studied physiology before ... there were two hundred and eight bones in the body. Now there are two hundred and thirty- eight.”
—Ellen Henrietta Swallow Richards (1842–1911)
“I have more in common with a Mexican man than with a white woman.... This opinion ... chagrins women who sincerely believe our female physiology unequivocally binds all women throughout the world, despite the compounded social prejudices that daily affect us all in different ways. Although women everywhere experience life differently from men everywhere, white women are members of a race that has proclaimed itself globally superior for hundreds of years.”
—Ana Castillo (b. 1953)
