Predicted to enable actin binding activity. Involved in several processes, including actin filament organization; cellular response to glucocorticoid stimulus; and negative regulation of long-term synaptic potentiation. Located in actin cytoskeleton; neuron projection; and synapse. Is expressed in diencephalon ventricular layer; hypothalamus ventricular layer; inner ear; and olfactory epithelium. Orthologous to human FAM107A (family with sequence similarity 107 member A). [provided by Alliance of Genome Resources, Apr 2022]
