Descriptions

E3 ubiquitin-protein ligase HACE1 (HACE1) is a protein involved in Golgi membrane fusion and regulation of small GTPases. It plays a key role as a regulator of Golgi membrane dynamics during the cell cycles, recruiting to Golgi membrane by Rab proteins and regulating postmitotic Golgi membrane fusion. Autoinhibition of HACE1 is controlled by dimerization that induces a configuration inhibiting the ubiquitin transfer from E2 to substrate. This inhibitory state is maintained by specific interactions between the N-helix of one subunit and the small wing of the HECT N-lobe of the adjacent subunit.

6 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
endoplasmic reticulum The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).
Golgi cisterna membrane The lipid bilayer surrounding any of the thin, flattened compartments that form the central portion of the Golgi complex.
Golgi membrane The lipid bilayer surrounding any of the compartments of the Golgi apparatus.
nuclear body Extra-nucleolar nuclear domains usually visualized by confocal microscopy and fluorescent antibodies to specific proteins.
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

3 GO annotations of molecular function

Name Definition
small GTPase binding Binding to a small monomeric GTPase.
ubiquitin protein ligase activity Catalysis of the transfer of ubiquitin to a substrate protein via the reaction X-ubiquitin + S -> X + S-ubiquitin, where X is either an E2 or E3 enzyme, the X-ubiquitin linkage is a thioester bond, and the S-ubiquitin linkage is an amide bond
ubiquitin-protein transferase activity Catalysis of the transfer of ubiquitin from one protein to another via the reaction X-Ub + Y --> Y-Ub + X, where both X-Ub and Y-Ub are covalent linkages.

8 GO annotations of biological process

Name Definition
cell cycle The progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. Canonically, the cell cycle comprises the replication and segregation of genetic material followed by the division of the cell, but in endocycles or syncytial cells nuclear replication or nuclear division may not be followed by cell division.
Golgi organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the Golgi apparatus.
membrane fusion The membrane organization process that joins two lipid bilayers to form a single membrane.
protein K48-linked ubiquitination A protein ubiquitination process in which a polymer of ubiquitin, formed by linkages between lysine residues at position 48 of the ubiquitin monomers, is added to a protein. K48-linked ubiquitination targets the substrate protein for degradation.
protein polyubiquitination Addition of multiple ubiquitin groups to a protein, forming a ubiquitin chain.
protein ubiquitination The process in which one or more ubiquitin groups are added to a protein.
regulation of cell migration Any process that modulates the frequency, rate or extent of cell migration.
ubiquitin-dependent protein catabolic process The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of a ubiquitin group, or multiple ubiquitin groups, to the protein.
