Protein Name:
Geranylgeranyl transferase type-2 subunit alpha 1
|
UniprotKB/SwissProt ID: Q8VYB7 (Q8VYB7)
Gene Name:
RGTA1
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Catalyzes the transfer of a geranylgeranyl moiety from geranylgeranyl diphosphate to both cysteines of Rab proteins with the C-terminal sequence -CCXX, CXXX, -XCCX and -XCXC, such as RABA1A, RABA2A, RABF2A and RABG2 (PubMed:26589801). In vitro, can prenylate PGGTI targets with the C-terminal Cys-aliphatic-aliphatic-X (CaaX) with leucine in the terminal position. Substrates with the C-terminal sequence -CSIL such as ARAC11/ROP1 or GG2/AGG2 are prenylated independently of REP and when the alpha subunit is associated with a beta subunit (RGTB1 or RGTB2) (PubMed:26589801)
