Other Information

**Key Characteristics** PAK3 is a 56-kDa protein that belongs to the PAK family of serine/threonine kinases. It is characterized by its ability to phosphorylate and activate downstream targets, including actin-binding proteins and RHO GTPases. PAK3 is highly expressed in the nervous system, particularly in neurons, glial cells, and immune cells such as macrophages and dendritic cells. **Pathways and Functions** PAK3 is involved in several key signaling pathways, including: 1. **Rho GTPase cycle**: PAK3 is activated by RAC1 and regulates the activity of RHO GTPases, which are essential for actin cytoskeleton organization and cell migration. 2. **Axon guidance**: PAK3 regulates axon guidance and axonogenesis by phosphorylating and activating downstream targets, such as MAPK and RHO GTPases. 3. **Synapse organization**: PAK3 is involved in the regulation of synapse formation and maintenance by phosphorylating and activating downstream targets, such as postsynaptic density proteins. 4. **Immune system**: PAK3 is expressed in immune cells and regulates immune responses by phosphorylating and activating downstream targets, such as MAPK and RHO GTPases. **Clinical Significance** Dysregulation of PAK3 has been implicated in various neurological and immunological disorders, including: 1. **Neurodegenerative diseases**: PAK3 has been implicated in Alzheimer's disease, Parkinson's disease, and Huntington's disease, where it regulates axon guidance and synapse formation. 2. **Immune disorders**: PAK3 has been implicated in autoimmune diseases, such as multiple sclerosis and rheumatoid arthritis, where it regulates immune responses and inflammation. 3. **Cancer**: PAK3 has been implicated in cancer development and progression, where it regulates cell migration and invasion. In conclusion, PAK3 is a versatile kinase regulator that plays a critical role in immune and neural function. Its dysregulation has been implicated in various neurological and immunological disorders, highlighting the importance of further research into the mechanisms of PAK3 signaling and its potential therapeutic targets. **References** * [1] Wang et al.

Database document:

This is a preview of the gene's schema. Only a few entries are kept for 'singleCellExpressions,' 'mRNAExpressions,' and other large data arrays for visualization purposes. You can zoom in with the mouse wheel for a closer view, and the text will adjust automatically if necessary. For the full schema, download it here.
