Gene Description

DCTN1 encodes p150Glued, the largest subunit of dynactin, the multiprotein complex that activates cytoplasmic dynein-1. p150Glued forms, with DCTN2 and DCTN3, the shoulder of the Arp1-filament-based dynactin complex and projects a long coiled-coil arm ending in an N-terminal CAP-Gly and basic domain. Through these regions it binds dynein intermediate chain, microtubules (preferentially tyrosinated) and plus-end tracking proteins EB1 and CLIP-170, so that dynactin, together with a cargo adaptor such as BICD2 or HOOK3, converts dynein into an ultra-processive minus-end-directed motor and loads it at microtubule plus ends. Dynein-dynactin transports vesicles, endosomes, lysosomes, retromer carriers and other organelles, drives retrograde axonal transport, and pulls on the nuclear envelope in nuclear positioning, neuronal nucleokinesis and prophase nuclear envelope breakdown. In mitosis p150Glued localizes to kinetochores, spindle poles and the cell cortex, where cortical dynein-dynactin positions and orients the spindle. A separate centrosomal pool at mother-centriole subdistal appendages anchors microtubules and supports centriole cohesion and primary cilium formation. The neuron-enriched full-length isoform (with CAP-Gly domain) also acts directly on microtubules, promoting nucleation and suppressing catastrophe. CAP-Gly domain mutations cause Perry syndrome and distal hereditary motor neuronopathy, and DCTN1 variants are associated with ALS susceptibility.

Existing Annotations Review

GO Term Evidence Action Reason
GO:0000132 establishment of mitotic spindle orientation
IBA
GO_REF:0000033
ACCEPT
Summary: IBA for establishment of mitotic spindle orientation; dynein-dynactin anchored at the cell cortex pulls on astral microtubules to orient the spindle, and human p150Glued has direct experimental support.
Reason: The PAINT node placement is consistent with conserved cortical dynein-dynactin function in spindle positioning (yeast, worm and human data). Human DCTN1 carries its own IMP (PMID:22327364), so the IBA reflects inherited function.

Plays a role in metaphase spindle orientation
PMID:22327364
We find that this signal comprises the spindle-pole-localized polo-like kinase (Plk1), which regulates dynein localization by controlling the interaction between dynein-dynactin and its upstream cortical targeting factors NuMA and LGN.

ACCEPT
Summary: Spindle orientation IMP in human cells; Plk1 controls cortical dynein-dynactin (including p150) and hence spindle position/orientation.
Reason: Full text shows asymmetric cortical dynactin/p150 localization and that dynein-dynactin at the cortex is controlled to orient the spindle. UniProt summarises this as a role in metaphase spindle orientation.

MARK AS OVER ANNOTATED
Summary: NAS to the broad term mitotic cell cycle from the original cloning paper of p150Glued.
Reason: The 1991 paper cloned the dynein-associated 150K polypeptide and only speculated about dynein roles in mitosis; more specific, experimentally supported mitotic processes (spindle orientation, prophase nuclear envelope breakdown) are annotated separately. The generic cell-cycle term adds little.
Supporting Evidence:
PMID:1828535
It is thought to be responsible for retrograde axonal transport and other aspects of organelle motility and may have a role in the poleward movement of mitotic chromosomes.
GO:0000776 kinetochore
IBA
GO_REF:0000033
ACCEPT
Summary: Kinetochore localization (IBA) of dynactin during mitosis is well established; dynein-dynactin is recruited to kinetochores by RZZ/Spindly.
Reason: Consistent with experimental data in human cells (IDA rows from PMID:19468067 and PMID:23027904).
Supporting Evidence:
PMID:19468067

ACCEPT
Summary: Kinetochore IDA from the human Spindly study, in which dynein/dynactin at kinetochores is the object of analysis.
Reason: The paper examines Spindly-dependent kinetochore recruitment of dynein/dynactin in human cells; kinetochore is a bona fide mitotic location of dynactin.

GO:0007097 nuclear migration
IBA
GO_REF:0000033
ACCEPT
Summary: IBA to nuclear migration. Dynein-dynactin moves nuclei toward microtubule minus ends in fungi, worms and vertebrate neurons; in migrating neurons nesprin/SUN complexes anchor dynein/dynactin (including p150) at the nuclear envelope.
Reason: The PAINT node (donors including C. elegans dnc-1) reflects conserved dynactin involvement in nuclear positioning. In mouse cortex, p150 co-precipitates with nesprin-1/2 and dynein/dynactin supplies the pulling force for nucleokinesis. DCTN1, as the dynein-binding and microtubule-binding subunit of the dynein activator, does part of the work of this process.
Supporting Evidence:
PMID:19874786
Our results indicate that the SUN-KASH complexes mediate the coupling between the nucleus and the centrosome, and provide anchors in the NE for cytoplasmic dynein/dynactin during neuronal migration.

PMID:15173193
There is a growing body of evidence that the dynein–dynactin complex associates with nuclear membranes in many cell types, and these complexes coupled to the nucleus may move in a minus end–directed fashion toward the centrosome.

REMOVE
Summary: Contributes_to sterol sensor activity (IDA, ORP1L study).
Reason: In this study the cholesterol sensor is ORP1L; p150Glued is the downstream effector whose recruitment to Rab7-RILP is controlled by ORP1L/VAP. DCTN1 has no sterol-binding domain and does not contribute to sensing sterol; the effect on p150Glued is a readout of the sensor, so this MF assignment is incorrect. The companion cholesterol-transport process rows from the same paper are marked over-annotated rather than removed, because p150Glued does take part in the late-endosome positioning that the process depends on, whereas sensing sterol is an activity it lacks.

REMOVE
Summary: NOT axonal transport, based on the absence of detectable transport inhibition in G59S p150Glued transgenic mice.
Reason: The experiment shows that one disease allele does not measurably impair bulk axonal transport in this model; it does not show that DCTN1 is not involved in axonal transport. Dynactin is widely documented as essential for dynein-driven (retrograde) axonal transport, and even the G59S study authors interpret a subtle loss of function as affecting retrograde axonal transport. The negative assertion is contradicted by the broader evidence.

Activation of cytoplasmic dynein motility by dynactin-cargo ...
NEW
Summary: Dynactin (with p150Glued as its dynein- and microtubule-binding projection) activates processive motility of mammalian cytoplasmic dynein together with cargo adaptors such as BICD2.
Reason: Purified mammalian dynein alone is poorly processive; dynein-dynactin-BICD2 complexes move robustly and processively, and BICD2 alone does not stimulate motility without dynactin. This dynein-activating function is the central molecular role of dynactin and is not represented in the existing annotation set. Because activation is a property of the whole dynactin complex, this is best asserted as contributes_to for DCTN1.
Supporting Evidence:
PMID:25035494
The addition of BicD2 to purified brain dynein did not stimulate processive motility, indicating a requirement for dynactin

Many organelle and mitotic functions are established for dynactin as a whole and should not be over-annotated as independent p150–cargo interactions.

Core Functions

As the dynein-binding subunit of dynactin, p150Glued contributes to activation of cytoplasmic dynein-1 into a processive minus-end-directed motor that transports membranous cargoes and organelles along microtubules.

    recruitment of the motor complex to the membrane-associated retromer requires the SNX6-p150(Glued) interaction
  • PMID:19874786
    Our results indicate that the SUN-KASH complexes mediate the coupling between the nucleus and the centrosome, and provide anchors in the NE for cytoplasmic dynein/dynactin during neuronal migration.

The p150Glued CAP-Gly and basic domains bind microtubules, tubulin and +TIPs, tethering dynein-dynactin to microtubule plus ends and, in neurons, promoting microtubule nucleation and suppressing catastrophe.

  • PMID:16505168
    we observed the binding of only half of the mutant p150Glued polypeptide to microtubules, suggesting that some portion of the mutant protein population is unavailable for binding to microtubules.

Supporting Evidence:

    We find that this signal comprises the spindle-pole-localized polo-like kinase (Plk1), which regulates dynein localization by controlling the interaction between dynein-dynactin and its upstream cortical targeting factors NuMA and LGN.

Suggested Questions for Experts

Q: Should DCTN1 carry an explicit contributes_to cytoskeletal motor activator activity (GO:0140660) annotation, given that dynein activation is a property of the assembled dynactin complex with a cargo adaptor?

Suggested experts: GO molecular function editors, dynein/dynactin biochemists

Q: Is the NOT axonal transport annotation (PMID:18364389) intended to capture only that the G59S allele does not impair bulk transport, and should it be withdrawn given that dynactin is required for retrograde axonal transport initiation?

Suggested experts: GO annotation QC, neuronal transport experts

Q: Which nucleokinesis contexts (radial migration, interkinetic nuclear migration, neural crest) have direct DCTN1-specific evidence, as opposed to evidence from dynactin disruption by dynamitin overexpression?

Suggested experts: neuronal migration biologists

Suggested Experiments

Experiment: Acute degron-mediated depletion of DCTN1 in migrating cortical neurons with live imaging of nucleus-centrosome coupling, rescued by p150 or p135 isoforms and by a CAP-Gly mutant.

Hypothesis: Nuclear translocation in neuronal nucleokinesis requires the dynein-activating function of dynactin but not the CAP-Gly microtubule-binding domain.

Type: live imaging with isoform rescue

Experiment: Single-molecule reconstitution of dynein-dynactin-BICD2 on nesprin-2-decorated membranes with p150 variants lacking CAP-Gly or CC1.

Hypothesis: p150 CC1 and the dynein-binding region are required for nuclear-envelope-anchored dynein force generation.

Type: in vitro reconstitution
