Summary
Protein kinases regulate neuronal migration, a key process in forming the mammalian cortex. Understanding these enzymes, like Cdk5 and JNKs, is crucial for neocortical development and function.
Area of Science:
- Neuroscience
- Developmental Biology
- Cell Biology
Background:
- The mammalian cortex forms via inside-out neuronal migration, essential for function.
- Neuronal migration relies on intracellular signaling, including protein phosphorylation.
- Extracellular cues modulate phosphorylation, impacting neuronal migration.
Purpose of the Study:
- To review the critical roles of protein kinases in regulating neuronal migration.
- To highlight specific kinases involved in key migratory steps.
Main Methods:
- This review synthesizes existing research on protein kinases and neuronal migration.
- Focuses on signaling pathways and cytoskeletal regulation.
Main Results:
- Protein phosphorylation is a key regulatory mechanism in neuronal migration.
- Specific protein kinases, including Cyclin-dependent kinase 5 (Cdk5) and c-Jun N-terminal kinases (JNKs), are vital for neuronal migration.
- These kinases are involved in critical steps like multipolar-bipolar transition and radial glia-guided locomotion.
Conclusions:
- Protein kinases are indispensable regulators of neuronal migration.
- Dysregulation of these kinases may impact cortical development and function.

19.3K
Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

01:19Cell Migration
7.6K
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

01:32Cytoskeletal Coordination in Cell Migration
5.8K
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker...

01:18Role of Myosin in Cell Migration
3.8K
Myosins are multimeric motor proteins involved in various cellular processes such as migration, adhesion, and proliferation. Myosin II is the most common type in animal cells, which binds and cross-links actin filaments.
Myosin II is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction....

01:07MAPK Signaling Cascades
9.5K
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

01:21Cell Polarization by Rho Proteins
4.2K
Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is essential to many processes such as embryogenesis, axon migration, glucose transport across epithelial cells, and directional cell migration. A migrating cell responds to intracellular or extracellular signals via molecular cascades that reorganize the actin cytoskeleton to establish this polarity. In these cells, the Rho family proteins Cdc42,...
