FEZ1

This gene is an ortholog of the C. elegans unc-76 gene, which is necessary for normal axonal bundling and elongation within axon bundles. Expression of this gene in C. elegans unc-76 mutants can restore to the mutants partial locomotion and axonal fasciculation, suggesting that it also functions in axonal outgrowth. The N-terminal half of the gene product is highly acidic. Alternatively spliced transcript variants encoding different isoforms of this protein have been described. [provided by RefSeq, Jul 2008]

Fasciculation And Elongation Protein Zeta 1

May be involved in axonal outgrowth as component of the network of molecules that regulate cellular morphology and axon guidance machinery. Able to restore partial locomotion and axonal fasciculation to C.elegans unc-76 mutants in germline transformation experiments. May participate in the transport of mitochondria and other cargos along microtubules.

Centrosome; Cell membrane. Colocalizes with both, alpha- and gamma-tubulin. Translocated from the plasma membrane to the cytoplasm by activation of the PKC zeta (By similarity).

Phosphorylated by protein kinase C zeta; which enhances interaction with UBE4B and polyubiquitination.
Polyubiquitinated in a UBE4B-dependent manner; which does not lead to proteasomal degradation and may be important for neurogenic activity. Polyubiquitin linkage seems to be mainly through Lys-26.
