Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in regulation of neuron projection development. Predicted to act upstream of or within several processes, including negative regulation of stress fiber assembly; positive regulation of lamellipodium assembly; and positive regulation of small GTPase mediated signal transduction. Predicted to be located in several cellular components, including growth cone; neuronal cell body; and nucleoplasm. Human ortholog(s) of this gene implicated in congenital nystagmus 1. Orthologous to human FRMD7 (FERM domain containing 7). [provided by Alliance of Genome Resources, Apr 2022]
