Dynein

Dynein

(Science: protein) large multimeric protein (600-800 kD) with atpase activity, constitutes the side arms of the outer microtubule doublets in the ciliary axoneme and is responsible for the sliding. Probably (together with kinesin) involved in microtubule associated movement elsewhere. Cytoplasmic dynein is map Ic.

Question about flagella

... use a rotary molecular motor to move their flagella. (Cilia too I think) Eukaryotes do not use a rotary system, they use microtubules with dynein "arms" that cause the microtubules to slide against each other and make the flagella as a whole move. So I guess my question is, how ...

Re: Microtubules and microfilaments can't operate independently?

well, microtubules are made up of proteins, specifically alpha and beta tubulins. they also act as substrates for other proteins like dynein and kinesin. so i guess they do need the help of proteins, besides the fact that they are also made of proteins. does that help? Oh, I know they're ...

increase speed Kinesin/dynein

Hello Does anyone have an idea of how you would increase de velocity of dynein or kinesin. (maybe increase the hydrolisation of ATP? or increase the individual step size? Thanks very much

Dyneins& Kinesins

i was wondering, what happends to a dynein (or a kinesin), when it reaches the end of the microtubule (when it has transported the cargo and its role is over). It is just destroyed or the microtubules are conected in a way that dynein can continue ...
