Dynein is a motor protein (also called molecular motor or motor molecule) in cells which converts the chemical energy contained in ATP into the mechanical energy of movement. Dynein transports various cellular cargo by "walking" along cytoskeletal microtubules towards the minus-end of the microtubule, which is usually oriented towards the cell center. Thus, they are called "minus-end directed motors." This form of transport is known as retrograde transport. In contrast, kinesins, which are motor proteins that move toward the microtubules' plus end, are called plus-end directed motors. ==Classification== Dyneins can be divided into two groups: cytoplasmic dyneins and axonemal dyneins, which are also called ciliary or flagellar dyneins. * axonemal * * heavy chain: DNAH1, DNAH2, DNAH3, DNAH5, DNAH6, DNAH7, DNAH8, DNAH9, DNAH10, DNAH11, DNAH12, DNAH13, DNAH14, DNAH17 * * intermediate chain: DNAI1, DNAI2 * * light intermediate chain: DNALI1 * * light chain: DNAL1, DNAL4 * cytoplasmic * * heavy chain: DYNC1H1, DYNC2H1 * * intermediate chain: DYNC1I1, DYNC1I2 * * light intermediate chain: DYNC1LI1, DYNC1LI2, DYNC2LI1 * * light chain: DYNLL1, DYNLL2, DYNLRB1, DYNLRB2, DYNLT1, DYNLT3 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dynein」の詳細全文を読む スポンサード リンク
