Rgl1 - ral guanine nucleotide dissociation stimulator,-like 1

This gene encodes a member of the Ras-like (Ral) -selective guanine nucleotide exchange factor (RalGEF) family of small GTPase activators which function both as downstream effectors of activated Ras GTPase and as regulators of certain Ral GTPases in the RalGEF - Ral GTPase signaling pathway. The encoded protein, like other RalGEFs, has an N-terminal ras exchanger motif domain, a catalytic CDC25 homology domain, and a C-terminal ras binding domain that stimulates guanine nucleotide exchange when bound to a Ral GTPase. RalGEF family members bridge the Ras and Ral signaling pathways and are thought to play a role in oncogenic transformation. Alternative splicing results in multiple transcript variants.
