General annotation (Comments)

Function

Plasma membrane-associated small GTPase which cycles between an active GTP-bound and an inactive GDP-bound state. In active state binds to a variety of effector proteins to regulate cellular responses. Involved in epithelial cell polarization processes. Causes the formation of thin, actin-rich surface projections called filopodia By similarity.

Enzyme regulation

Regulated by guanine nucleotide exchange factors (GEFs) which promote the exchange of bound GDP for free GTP, GTPase activating proteins (GAPs) which increase the GTP hydrolysis activity, and GDP dissociation inhibitors which inhibit the dissociation of the nucleotide from the GTPase By similarity.

Subunit structure

Interacts with CDC42EP1, CDC42EP2, CDC42EP3, CDC42EP4, CDC42EP5, CDC42SE1, CDC42SE2, PARD6A, PARD6B and PARD6G (in a GTP-dependent manner). Interacts with activated CSPG4 and with BAIAP2. Interacts with Zizimin1/DOCK9 and Zizimin2/DOCK11, which activate it by exchanging GDP for GTP. Interacts with NET1 and TCGAP/SNX26. Part of a complex with PARD3, PARD6A or PARD6B and PRKCI or PRKCZ. The GTP-bound form interacts with CCPG1 By similarity.

Subcellular location

Cell membrane; Lipid-anchor; Cytoplasmic side Potential.

Sequence similarities

Belongs to the small GTPase superfamily. Rho family. CDC42 subfamily.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q8CFN2-1)

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.
Note: No experimental confirmation available.
Isoform 2 (identifier: Q8CFN2-2)

The sequence of this isoform differs from the canonical sequence as follows:
     182-191: PKKSRRCVLL → TQPKRKCCIF
