General annotation (Comments)

Function

Acts upstream of PAK1 to regulate the actin cytoskeleton, adhesion turnover and increase cell migration. Stimulates quiescent cells to reenter the cell cycle. Has no detectable GTPase activity but its high intrinsic guanine nucleotide exchange activity suggests it is constitutively GTP-bound. Plays a role in the regulation of cell morphology and cytoskeletal organization. Required in the control of cell shape. Ref.1 Ref.14 Ref.15 Ref.16 Ref.17

Cofactor

Magnesium. Ref.14

Subunit structure

Interacts with PAK3. Interacts with ARHGAP30 in a GTP-independent manner. In its GTP-loaded conformation, interacts with ARHGAP31. Interacts with PTK2B/PYK2. Ref.15 Ref.16 Ref.18

Subcellular location

Cell membrane; Lipid-anchor; Cytoplasmic side. Golgi apparatus membrane; Lipid-anchor. Cell junctionfocal adhesion. Cell projectionpodosome. Note: Localizes to podosomes in SRC-transformed cells. Ref.13 Ref.14 Ref.15 Ref.16

Tissue specificity

Ubiquitously expressed in all tissues examined. Expressed at high levels in the stomach, small intestine, brain, skeletal muscle and placenta. Ref.1 Ref.3

Post-translational modification

Tyrosine phosphorylated by SRC in response to PTK2B/PYK2 activation. Ref.16

Sequence similarities

Belongs to the small GTPase superfamily. Rho family. Ref.14

Binary interactions

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 Ref.1 Ref.2 Ref.3 Ref.5 Ref.6 Ref.7 Ref.8 Ref.12 (identifier: Q7L0Q8-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 Ref.9 (identifier: Q7L0Q8-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-61: Missing.
     62-66: KTSLV → MTNIG
Note: No experimental confirmation available.
