This entry represents the C-terminal region of domain I from Rab escort proteins 1/2 (RAE1/2, also known as Rab proteins geranylgeranyltransferase component A 1/2) which are the substrate-binding subunit of the Rab geranylgeranyltransferase (GGTase) complex [1,2]. These proteins bind unprenylated Rab proteins and presents the substrate peptide to the catalytic component B and remains bound to it after the geranylgeranyl transfer reaction.	Domain

Rab geranylgeranyl transferase (RabGGT) catalyses the addition of two geranylgeranyl groups to the C-terminal cysteine residues of Rab proteins, which is crucial for membrane association and function of these proteins in intracellular vesicular trafficking [1]. This domain is inserted between Pfam:PF01239 repeats. This domain adopts an Ig-like fold and is thought to be involved in protein-protein interactions and might be involved in the recognition and binding of REP [1].	Domain
