Automated description from the Alliance of Genome Resources (Release 5.3.0)
Enables guanyl-nucleotide exchange factor activity. Involved in associative learning. Acts upstream of or within regulation of catalytic activity. Predicted to be located in several cellular components, including basolateral part of cell; brush border membrane; and distal axon. Predicted to be active in plasma membrane. Predicted to colocalize with cortical actin cytoskeleton. Is expressed in brain; heart; lung; and metanephros. Orthologous to human RAPGEF3 (Rap guanine nucleotide exchange factor 3).
