Protein attributes

Sequence length	439 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	GTPase activator for the Rho, Rac and Cdc42 proteins, converting them to the putatively inactive GDP-bound state. Cdc42 seems to be the preferred substrate.
Subunit structure	Found in a complex with XPO7, EIF4A1, ARHGAP1, VPS26A, VPS29, VPS35 and SFN. Interacts with BNIPL. Ref.7 Ref.8
Subcellular location	Cytoplasm.
Tissue specificity	Ubiquitous.
Sequence similarities	Contains 1 CRAL-TRIO domain. Contains 1 Rho-GAP domain.
Sequence caution	The sequence AAA16142.1 differs from that shown. Reason: Erroneous initiation.
