FARP2 (FERM, ARH/RhoGEF, And Pleckstrin Domain Protein 2): FARP2 is a signaling protein that plays a key role in neuronal development and synaptic plasticity. It regulates dendritic spine formation and actin cytoskeleton remodeling by acting as a guanine nucleotide exchange factor for small GTPases. Through these pathways, FARP2 influences neuronal connectivity and function. Changes in FARP2 expression or activity are linked to neurological disorders, underscoring its importance in brain development and synaptic regulation.
