Accurate balance of the polarity kinase MARK2/Par-1 is required for proper cortical neuronal migration.

Radial neuronal migration is key in structuring the layered cortex. Here we studied the role of MARK2/Par-1 in this process. The dual name stands for the MAP/microtubule affinity-regulating kinase 2 (MARK2) and the known polarity kinase 1 (Par-1). Reduced MARK2 levels using in utero electroporation resulted in multipolar neurons stalled at the intermediate zone border. Reintroduction of the wil...

Protein kinase MARK/PAR-1 is required for neurite outgrowth and establishment of neuronal polarity.

Protein kinases of the microtubule affinity-regulating kinase (MARK) family were originally discovered because of their ability to phosphorylate certain sites in tau protein (KXGS motifs in the repeat domain). This type of phosphorylation is enhanced in abnormal tau from Alzheimer brain tissue and causes the detachment of tau from microtubules. MARK-related kinases (PAR-1 and KIN1) occur in var...

16p11.2 is required for neuronal polarity

Since Autism Spectrum Disorder (ASD) is strongly associated with chromosomal abnormalities of 16p11.2, and Autism has been linked to neuronal polarity defect, our study aimed to explore the role of 16p11.2 genes in regulating neuronal polarity. We performed a neuronal polarity assay in a high throughput manner for candidate genes at 16p11.2. Our most interesting finding was that three 16p11.2 c...

Spatial segregation of polarity factors into distinct cortical clusters is required for cell polarity control

Cell polarity is regulated by evolutionarily conserved polarity factors whose precise higher-order organization at the cell cortex is largely unknown. Here we image frontally the cortex of live fission yeast cells using time-lapse and super-resolution microscopy. Interestingly, we find that polarity factors are organized in discrete cortical clusters resolvable to ~50-100 nm in size, which can ...

The adhesion molecule TAG-1 is required for proper migration of the superficial migratory stream in the medulla but not of cortical interneurons.

The neural cell adhesion molecule TAG-1 has been implicated in the tangential migration of neurons of the caudal medulla and of cortical interneurons. In the former case, protein is expressed by the neurons as they migrate, and blocking its function results in altered and reduced migration in vitro. In the latter case, protein is expressed, in part, by the pathway the interneurons use to reach ...
