Descriptions

Formins are conserved actin nucleators responsible for the assembly of diverse actin structures. In a study with Formin-3, the autoinhibition mechanism involves the intramolecular interaction between N-terminal DID domain and C-terminal DAD domain. This interaction is disrupted by Rho GTPase that is able to bind to the DID domain.

4 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
cytoskeleton A cellular structure that forms the internal framework of eukaryotic and prokaryotic cells. The cytoskeleton includes intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles.
macropinocytic cup cytoskeleton The part of the cortical actin cytoskeleton that forms part of a macropinocytic cup.
phagocytic cup An invagination of the cell membrane formed by an actin dependent process during phagocytosis. Following internalization it is converted into a phagosome.

2 GO annotations of molecular function

Name Definition
actin filament binding Binding to an actin filament, also known as F-actin, a helical filamentous polymer of globular G-actin subunits.
profilin binding Binding to profilin, an actin-binding protein that forms a complex with G-actin and prevents it from polymerizing to form F-actin.

5 GO annotations of biological process

Name Definition
actin filament network formation The assembly of a network of actin filaments; actin filaments on different axes and with differing orientations are crosslinked together to form a mesh of filaments.
cortical actin cytoskeleton organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of actin-based cytoskeletal structures in the cell cortex, i.e. just beneath the plasma membrane.
positive regulation of actin filament polymerization Any process that activates or increases the frequency, rate or extent of actin polymerization.
positive regulation of macropinocytosis Any process that activates or increases the frequency, rate or extent of macropinocytosis.
positive regulation of phagocytosis, engulfment Any process that activates or increases the frequency, rate or extent of the internalization of bacteria, immune complexes and other particulate matter or of an apoptotic cell by phagocytosis.
