CC   -!- FUNCTION: Plasma membrane-associated small GTPase which cycles
CC       between an active GTP-bound and an inactive GDP-bound state. In
CC       active state binds to a variety of effector proteins to regulate
CC       cellular responses. Involved in epithelial cell polarization
CC       processes. Regulates the bipolar attachment of spindle
CC       microtubules to kinetochores before chromosome congression in
CC       metaphase. Plays a role in the extension and maintenance of the
CC       formation of thin, actin-rich surface projections called
CC       filopodia. Mediates CDC42-dependent cell migration. Required for
CC       DOCK10-mediated spine formation in Purkinje cells and hippocampal
CC       neurons. Facilitates filopodia formation upon DOCK11-activation.
CC       Also plays a role in phagocytosis through organization of the F-
CC       actin cytoskeleton associated with forming phagocytic cups.
CC       {ECO:0000250|UniProtKB:P60766, ECO:0000250|UniProtKB:P60953}.
CC   -!- ACTIVITY REGULATION: Regulated by guanine nucleotide exchange
CC       factors (GEFs) which promote the exchange of bound GDP for free
CC       GTP, GTPase activating proteins (GAPs) which increase the GTP
CC       hydrolysis activity, and GDP dissociation inhibitors which inhibit
CC       the dissociation of the nucleotide from the GTPase.
CC       {ECO:0000250|UniProtKB:P60766}.
CC   -!- SUBUNIT: Interacts with CDC42EP1, CDC42EP2, CDC42EP3, CDC42EP4,
CC       CDC42EP5, CDC42SE1, CDC42SE2, PARD6A, PARD6B and PARD6G (in a GTP-
CC       dependent manner). Interacts with activated CSPG4 and with BAIAP2.
CC       Interacts with DOCK11/Zizimin2; the interaction activates CDC42 by
CC       exchanging GDP for GTP. Interacts with DOCK9; the interaction
CC       activates CDC42 by exchanging GDP for GTP. Interacts with DOCK8
CC       (via DHR-2 domain); the interaction activates CDC42 by exchanging
CC       GDP for GTP. Interacts with IQGAP1. Interacts with NET1 and
CC       ARHGAP33/TCGAP. Part of a complex with PARD3, PARD6A or PARD6B and
CC       PRKCI or PRKCZ. The GTP-bound form interacts with CCPG1. Interacts
CC       with USP6. Interacts with NEK6. Part of a collagen stimulated
CC       complex involved in cell migration composed of CDC42, CRK, TNK2
CC       and BCAR1/p130cas. Interacts with ITGB1BP1. Interacts with
CC       ARHGDIA; this interaction inactivates and stabilizes CDC42.
CC       Interacts with ARHGDIB; this maintains CDC42 in the inactive, GDP-
CC       bound form. Interacts in (GTP-bound form) with FNBP1L and ABI1,
CC       but only in the presence of FNBP1L. {ECO:0000250|UniProtKB:P60766,

CC       prometaphase cells. Moves to the central spindle as cells
CC       progressed through anaphase to telophase. Localizes at the end of
CC       cytokinesis in the intercellular bridge formed between two
CC       daughter cells. Its localization is regulated by the activities of
CC       guanine nucleotide exchange factor ECT2 and GTPase activating
CC       protein RACGAP1. Colocalizes with NEK6 in the centrosome. In its
CC       active GTP-bound form localizes to the leading edge membrane of
CC       migrating dendritic cells. {ECO:0000250|UniProtKB:P60766,
