Cell localization:Cell membrane, Lipid-anchor, Cytoplasmic side. Cytoplasm, cytoskeleton. Cleavage furrow. Cytoplasm, cell cortex . Midbody. Cell projection, lamellipodium . Cell projection, dendrite . Nucleus . Localized to cell-cell contacts in calcium-treated keratinocytes (By similarity). Translocates to the equatorial region before furrow formation in a ECT2-dependent manner. Localizes to the equatorial cell cortex (at the site of the presumptive furrow) in early anaphase in an activated form and in a myosin- and actin-independent manner. ..This gene encodes a member of the Rho family of small GTPases, which cycle between inactive GDP-bound and active GTP-bound states and function as molecµLar switches in signal transduction cascades. Rho proteins promote reorganization of the actin cytoskeleton and regµLate cell shape, attachment, and motility. Overexpression of this gene is associated with tumor cell proliferation and metastasis. MµLtiple alternatively spliced variants have been identified. [provided by RefSeq, Sep 2015],
