Human Drebrin 1 (DBN1) interaction partners

1. Lack of drebrin leads to the dysfunction of cell-cell communication, resulting in aberrant migration of metastatic cancer cells, aberrant synaptic function in dementia, and rupture of endothelial integrity.

2. One candidate pathway coupling actin filaments to microtubules consists of the actin filament-binding protein drebrin and the microtubule-binding +TIP protein EB3 (show MAPRE3 Antibodies). This pathway is regulated proximally by cyclin-dependent kinase 5 (show CDK5 Antibodies) phosphorylation of drebrin but the upstream elements in the pathway have yet to be identified.

3. These observations indicate that drebrin loss in dendritic spines occurs at the prodromal stage of Alzheimer's disease (AD), before the density and morphology of dendritic spines change. Quantitation of drebrin may be a possible tool for diagnosing the prodromal stage of AD, before dementia development in AD.

4. Taking into account that connexin-43 (Cx43 (show GJA1 Antibodies)) (together with Cx30 (show GJB6 Antibodies)) is heavily expressed in astrocytes and that drebrin supports cell-cell contacts, the understanding of details of how brain cells live and die reveals molecular pathology involved in neurodegeneration, Alzheimer's disease (AD), other cognitive disorders, and aging

5. further studies on drebrin and its binding proteins will be of great importance to elucidate the pathologies of various diseases and may contribute to their medical treatment and diagnostics development.

6. through its interaction with CXCR4 (show CXCR4 Antibodies) and the actin cytoskeleton, drebrin regulates T cell activation. CD4 (show CD4 Antibodies)(+) T cells are one of the main targets for the human immunodeficiency virus (HIV)-1.

7. Our work has shown that the immunosuppressant compound BTP2, which blocks Ca(2 (show CA2 Antibodies)+) influx into cells, interacts with the actin-reorganizing protein, drebrin. Here we review the role of drebrin in the regulation of calcium signaling, with a focus on immune cells.

8. Upregulation of drebrin was noted in several types of cancers, e.g., basal cell carcinomas for which it may serve as marker, liver metastases of colon carcinomas, and bladder cancer, suggesting that it is involved in regulating actin dynamics during tumor development, progression, and metastasis.

9. drebrin has to be added to the list of actin-binding proteins regulating actin dynamics of mesangial cell processes and foot processes of podocytes. It will be important to determine its role in hereditary and acquired glomerulopathies.

10. these results contribute to the current understanding of cell-cell junction regulation, introducing a new function of drebrin as a stabilizer of endothelial integrity.

Mouse (Murine) Drebrin 1 (DBN1) interaction partners

1. Drebrin A is highly enriched in dendritic spines, but its effects on actin morphology, dynamics, and interplay with other actin regulators are yet to be clarified. Here we review recent advances in understanding drebrin effects on actin morphology and dynamics.

2. Drebrin A can be found co-clustering with NR2B (show GRIN2B Antibodies)-containing NMDARs at the plasma membrane, while NR2A (show GRIN2A Antibodies)-containing NMDARs co-traffic into the spine cytoplasm but do not co-cluster at the plasma membrane.

3. these findings suggest that during cell migration drebrin is involved in retraction processes but not in lamellipodia formation. The novel, sizable juxtanuclear drebrin-enriched zone remains to be characterized in detail with respect to its molecular assembly and functions.

4. bn1 (show CCR6 Antibodies) expression is induced during myoblast differentiation, in a p38 MAP kinase (show MAPK14 Antibodies)- and MyoD (show MYOD1 Antibodies)- dependent manner. RNAi-mediated depletion of drebrin, or treatment with a chemical drebrin inhibitor, resulted in a similar phenotype in myoblasts: defective differentiation, with low levels of early and late differentiation markers and inefficient production of myofibers.

5. Study determines the specific roles of drebrin in the regulation of the axonal cytoskeleton, and provides evidence that drebrin contributes to the coordination of the actin and microtubule cytoskeleton during the initial stages of axon branching.

6. Drebrin reduces SMC (show DYM Antibodies) activation through its interaction with the actin cytoskeleton but independently of its interaction with Homer (show HOMER1 Antibodies) scaffolds to prevent neointima formation.

7. Data suggest further studies to elucidate the effect of drebrin (Dbn) on the development and progression of Alzheimer's disease (AD).

8. Study demonstrated that isoform conversion of drebrin is critical, and that drebrin A is indispensable for adult hippocampal synaptic plasticity and hippocampus-dependent fear learning; the phenotype of drebrin A knockout mice suggests functional differences between drebrin A and drebrin E

9. These findings provide unprecedented experimental support for a role of drebrin in the regulation of memory-related synaptic plasticity and neurotransmitter receptor (show GRIN1 Antibodies) signaling

10. Dbn1 regulates systemic anaphylaxis and IgE/Fcgr1-induced degranulation in mast cells by regulating actin reorganization and actin dynamics.
