Multiple sclerosis: Difference between revisions

Interferon alpha has a very similar structure to interferon beta. It, too, has many <scene name='Multiple_sclerosis/Ifna_labeled/1'>identifiable regions</scene> with two <scene name='Multiple_sclerosis/Ifna_disulfide_bonds/1'>disulfide bonds</scene>: one between the <scene name='Multiple_sclerosis/Ifna_disulfide_bondsn-e/1'>N-terminus and Helix E</scene>, and the other between <scene name='Multiple_sclerosis/Ifna_disulfide_bonds_ab-g/1'>Loop AB and Helix G</scene>. It has seven <scene name='Multiple_sclerosis/Ifna_alphahelices/1'>alpha helices</scene>, as compared to the five of interferon-β, and therefore has several more <scene name='Multiple_sclerosis/Ifna_loops_regions/1'>loop regions.</scene> The helices A, C, and F run <scene name='Multiple_sclerosis/Ifna_parallelacf/1'>parallel</scene> to one another, and anti-parallel to B, E, and G which run <scene name='Multiple_sclerosis/Ifna_parallel_beg/1'>parallel</scene> to each other.
