cd00153: RalGDS_RA (this model, PSSM-Id:176351 is obsolete and has been replaced by 340449)
Ubiquitin domain of RalGDS-like factor (RLF) and related proteins
This CD represents the C-terminal Ras-associating (RA) domain of three closely related guanine-nucleotide exchange factors (GEF's), Ral guanine nucleotide dissociation stimulator (RalGDS), RalGDS-like (RGL), and RalGDS-like factor (RLF). The RalGDS proteins are downstream effectors of the Ras-related protein Ral, providing a mechanism for Ral activation by extracellular signals. The RA domain is structurally similar to ubiquitin and exists in a number of other signalling proteins including AF6, rasfadin, SNX27, CYR1, and STE50.
