The minus-end-directed microtubule motor cytoplasmic dynein requires the dynactin complex for in vivo functions. The backbone of the vertebrate dynactin complex is the Arp1 (actin-related protein 1) mini-filament whose barbed end binds to the ...

Cryo‐EM reveals the complex architecture of dynactin's shoulder region and pointed end
Dynactin is a 1.1 MDa complex that activates the molecular motor dynein for ultra‐processive transport along microtubules. In order to do this, it forms a tripartite complex with dynein and a coiled‐coil adaptor.

Spindly is required for rapid migration of human cells
Dynein is the sole processive minus-end-directed microtubule motor found in animals. It has roles in cell division, membrane trafficking, and cell migration.

Regulation of dynein‐dynactin‐driven vesicular transport [PDF]
Most of the long‐range intracellular movements of vesicles, organelles and other cargoes are driven by microtubule (MT)‐based molecular motors. Cytoplasmic dynein, a multisubunit protein complex, with the aid of dynactin, drives transport of a wide variety of cargoes towards the minus end of MTs.

Lis1 activates dynein motility by modulating its pairing with dynactin
Lissencephaly-1 (Lis1) is a key cofactor for dynein-mediated intracellular transport towards the minus-ends of microtubules. It remains unclear whether Lis1 serves as an inhibitor or an activator of mammalian dynein motility.

Regulation of mitochondria-dynactin interaction and mitochondrial retrograde transport in axons
Mitochondrial transport in axons is critical for neural circuit health and function. While several proteins have been found that modulate bidirectional mitochondrial motility, factors that regulate unidirectional mitochondrial transport have been harder ...

On and off controls within dynein–dynactin on native cargoes
Significance The dynein–dynactin nanomotor is required for vastly diverse cellular functions, including cell division and cargo transport. Why dynactin interacts separately with the dynein motor and with microtubules is poorly understood and ...

New insights into the mechanism of dynein motor regulation by lissencephaly-1
Lissencephaly (‘smooth brain’) is a severe brain disease associated with numerous symptoms, including cognitive impairment, and shortened lifespan. The main causative gene of this disease – lissencephaly-1 (LIS1) – has been a focus of intense scrutiny ...

Dynactin: Coordinating Motors with Opposite Inclinations [PDF]
In eukaryotic cells, many organelles are transported bidirectionally along microtubules by kinesin and dynein. These opposite-polarity motors appear to be coordinated to avoid interfering with each other's function. New work has provided the first molecular insight into how such coordination might occur.

Lissencephaly-1 is a context-dependent regulator of the human dynein complex
The cytoplasmic dynein-1 (dynein) motor plays a central role in microtubule organisation and cargo transport. These functions are spatially regulated by association of dynein and its accessory complex dynactin with dynamic microtubule plus ends. Here, we
