Gene Description

Dynamin-1 is a large, predominantly neuronal GTPase that converts nucleotide hydrolysis into membrane remodeling during endocytosis. Its pleckstrin-homology domain binds phosphoinositides, its stalk supports self-assembly, and its proline-rich tail recruits SH3-domain partners. Assembly at membrane necks couples GTPase-domain interactions to constriction and vesicle scission, supporting receptor-mediated uptake and presynaptic membrane retrieval. Dynamin-1 also influences endocytic pit and vesicle dimensions. Alternative splicing changes an internal segment and the C-terminal tail; pathogenic variants can disrupt neuronal membrane trafficking and cause developmental and epileptic encephalopathy.

KEEP AS NON CORE
Summary: UV-dependent mRNA capture provides limited positive RNA-binding evidence.
Reason: The original author thesis Table S1 (PDF page 147) identifies DNM1 in class III: one experiment passes the study's threefold enrichment criterion, while the other two measurements are unavailable. Methods 3.5 uses UV crosslinking in HEK293 cells followed by denaturing oligo(dT) capture. This is positive screen evidence for RNA contact, rather than an inference from ordinary co-purification. Results 4.8 validates selected class I/II candidates; DNM1 was not tested individually, so its absence from that panel is not a failed validation. Limited replication and the unestablished physiological role justify non-core retention; neither proves the binding assertion exceeds the evidence.

Summary: Specify the membrane-scission GTPase motor activity.
Reason: Purified dynamin1 was assayed with SNX9; full-length SNX9 stimulated its GTP turnover, whereas the isolated SH3 domain bound without equivalent stimulation. The endogenous cell co-IP in that paper concerns DNM2 and is not needed for this catalytic conclusion. Human fission and nucleotide-linked structural rotation justify the narrower GO:1990606 classification; its mechanochemical evidence and species limits are detailed in the source guide. This does not assign every mechanical measurement to this assay or every natural splice product.

Summary: NCK1 association is mapped to its SH3 region.
Reason: IntAct preserves a positive pull-down and co-IP for this literal human pair. Its separately annotated sufficient-binding region on NCK1 spans residues 182–260, encompassing the official third SH3 domain at 190–252. Together with the source abstract, this supports SH3-domain recognition rather than an invented adaptor function for DNM1. The parent-protein checksum does not identify the length of the binding reagent.

Reason: The recovered original reports direct, nucleotide-dependent binding of dynamin1 to purified bovine Hsc70 and recombinant auxilin, including controls that distinguish independent binding from an unfolded chaperone substrate. This source row names both P19120 and Q27974. A single Hsp70-specific replacement would omit its auxilin component, and the assay does not make DNM1 a chaperone. The insect-cell dynamin reagent is not mapped to a current natural splice product.

Reason: The original Methods specifies human dynamin1 cDNA. Tagged FBP17 and its isolated SH3 fragment associate with DNM1; deleting the SH3 region or introducing P597L prevents association, with GST-domain pull-down corroboration. These domain-dependent experiments support the narrower term. They are not a purified full-length pair affinity measurement.

Reason: Purified full-length SNX9 and its SH3 domain bind recombinant dynamin1; deletion of the dynamin proline-rich domain or SNX9 SH3 region disrupts binding.

Reason: The original Methods explicitly identifies the human pcDNA-dynamin1 construct. Purified GST-NOSTRIN/SH3 baits recover DNM1 from transfected cell lysate, whereas the SH3 deletion does not; this mapping supports SH3-domain binding. The target was not purified in that pull-down, and the separate endogenous dynamin2 co-IP must not be relabeled as human DNM1 evidence.

Reason: Human HEK-cell reciprocal co-IP supports the literal NOS3/eNOS–DNM1 association and its nitric-oxide dependence.

Summary: A defined dynamin peptide binds the GRB2 SH3 domain.
Reason: The exact IntAct peptide-array record identifies the GRB2 SH3 region 156–215 and the DNM1 sufficient-binding segment 780–792. This directly supports SH3-domain binding with a peptide-reagent limit; it does not establish full-length affinity or stoichiometry in cells.

The separate mouse/human tissue AP-MS experiments are not pair-specific validation of this Y2H result, and no narrower partner-recognition activity is established.

Reason: The recovered original uses human cDNAs and shows DNM1 co-IP with SNX33 but not its SH3-deletion mutant, with unrelated protein controls (Figure 7A). The GST-SH3 experiment in Figure 7B principally pulls down endogenous DNM2 and is not a purified DNM1 assay. The target-specific deletion mapping nevertheless supports SH3-domain binding.

Reason: Figure 7A of the original explicitly includes human SNX9–DNM1 co-IP. Direct purified-domain and deletion experiments in 15703209 establish the narrower SH3 interface. The present paper does not independently measure that interface or assign every SNX33 perturbation result to SNX9.

Reason: The source tests a human LRRK2 N-terminal fragment in Y2H and independently confirms human full-length LRRK2–DNM1 co-IP; separate mouse dynamin constructs are labeled as such. LRRK2 is an experimentally established protein kinase. GO:0019901 describes binding to that protein class, not binding to its catalytic domain or DNM1-mediated kinase regulation.

Summary: Endocytosis is retained through its more informative receptor-mediated descendant.
Reason: The original uses GFP-Dynamin1 WT/K44A in embryonic-day18 rat hippocampal neurons. K44A blocks Caspr2 internalization and reduces EEA1-positive vesicles. Human DNM1 biochemical fission establishes the performed step independently, so this is not merely a downstream disease association. The host neurons are rat and the methods cite the historical construct without resolving a current splice accession. The broad term is true, but GO:0006898 receptor-mediated endocytosis is an asserted strict descendant that already captures the endocytic role at this level.

Reason: The original supplementary Methods uses rat-brain dynamin purified with an SH3 affinity reagent and reports confirmation of selected experiments with purified human dynamin1 from baculovirus.

Reason: The cached abstract reports that dominant-negative dynamin-1 and arrestin-3 inhibit PMA- and SDF-1alpha-induced CXCR4 internalization in transfected COS-1 and HEK-293 cells. Full Methods were not recovered, so the dynamin mutant identity and natural splice product are not assigned.

Reason: In the actual rat-neuron experiment, GFP-Dynamin1 K44A prevents formation of the EEA1-positive early-endosome pattern while WT permits Caspr2 delivery.

It does not establish a second independent endosome-building molecular activity.

Reason: The human leaf descends from PTN000902093; the fly shibire donor has a curated experimental budding annotation, with temperature-sensitive depletion of synaptic vesicles explicitly described in 15014125. Mouse hippocampal loss of Dnm1 also impairs retrieval, and human DNM1 rescues the measured endocytic fluorescence response.

Summary: GTP-dependent membrane severing is the defining directly measured activity.
Reason: The original reconstitutes non-leaky nanotube closure/fission with dynamin and distinguishes hydrolyzable GTP from GTPgammaS controls.

DNM1 performs the membrane-remodeling work rather than being cargo required for the process.

Core Functions

DNM1 couples GTP hydrolysis to oligomeric membrane remodeling and scission at endocytic necks. PH-domain recognition of phosphatidylinositol-4,5-bisphosphate anchors the assembly to the bilayer. GTPase-domain association stimulates hydrolysis, while nucleotide-linked conformational changes and the membrane-bound polymer promote neck constriction and severing.

Suggested Questions for Experts

Q: Which natural DNM1 splice products are responsible for the measured regulatory and membrane-remodeling differences under physiological neuronal conditions?

Q: Does DNM1 directly participate in clathrin cage assembly, or does its pre-fission effect on pit dimensions arise through other membrane-remodeling or recruitment steps?

Q: Can the DNM1 peptide/protein-group entry in the EPS-urine extracellular-vesicle dataset be recovered and independently verified?
