Function

Peripheral membrane component of the cis-Golgi stack that acts as a membrane skeleton that maintains the structure of the Golgi apparatus, and as a vesicle thether that facilitates vesicle fusion to the Golgi membrane (Probable) (PubMed:16489344). Required for normal protein transport from the endoplasmic reticulum to the Golgi apparatus and the cell membrane (By similarity). Together with p115/USO1 and STX5, involved in vesicle tethering and fusion at the cis-Golgi membrane to maintain the stacked and inter-connected structure of the Golgi apparatus. Plays a central role in mitotic Golgi disassembly: phosphorylation at Ser-37 by CDK1 at the onset of mitosis inhibits the interaction with p115/USO1, preventing tethering of COPI vesicles and thereby inhibiting transport through the Golgi apparatus during mitosis (By similarity). Also plays a key role in spindle pole assembly and centrosome organization (PubMed:26165940). Promotes the mitotic spindle pole assembly by activating the spindle assembly factor TPX2 to nucleate microtubules around the Golgi and capture them to couple mitotic membranes to the spindle: upon phosphorylation at the onset of mitosis, GOLGA2 interacts with importin-alpha via the nuclear localization signal region, leading to recruit importin-alpha to the Golgi membranes and liberate the spindle assembly factor TPX2 from importin-alpha. TPX2 then activates AURKA kinase and stimulates local microtubule nucleation. Upon filament assembly, nascent microtubules are further captured by GOLGA2, thus linking Golgi membranes to the spindle (PubMed:19242490, PubMed:26165940). Regulates the meiotic spindle pole assembly, probably via the same mechanism (By similarity). Also regulates the centrosome organization (PubMed:18045989, PubMed:19109421). Also required for the Golgi ribbon formation and glycosylation of membrane and secretory proteins (PubMed:16489344, PubMed:17314401).

Activity summary

GM130 also known as Golgi matrix protein 130 kDa or GM-130 plays an important role in the organization of the Golgi apparatus. The GM130 protein is vital for maintaining the structure of the Golgi serving as a Golgi marker for researchers. Its molecular weight is approximately 130 kDa. You will commonly find GM130 expressed in cells localizing to the cis-Golgi network. As a Golgi marker it serves as an indication of the integrity and positioning of the Golgi apparatus in the cell.

Biological function summary

GM130 serves as a structural component within the Golgi matrix. It interacts with other proteins such as GRASP65 to form a complex which is essential for Golgi stacking and maintenance of Golgi architecture. This interaction helps regulate transport processes inside cells. GM130 proteins help formation of mini-stacks and transitioning of vesicles. In cells GM130 plays a significant role to maintain efficient protein trafficking through the Golgi network.

Pathways

GM130 interacts with proteins like Rab1 during the vesicular transport pathway. It plays a part in the transport of proteins from the endoplasmic reticulum to the Golgi apparatus. Another related pathway involves SNARE proteins whereby GM130 contributes to membrane docking and fusion events. Through these interactions GM130 modulates the fidelity and specificity of molecular cargo transport within the cell.

Associated diseases and disorders

GM130 has a connection to neurodegenerative diseases such as frontotemporal dementia. Disruption in GM130 proteins affects Golgi structure and function potentially leading to protein trafficking defects associated with the disorder. GM130 also relates to Alzheimer's disease through its interaction with tau protein. Alterations in GM130's function can influence tau pathology contributing to disease progression.

    Immunocytochemistry/ Immunofluorescence - Alexa Fluor® 594 Anti-GM130 antibody [EP892Y] - cis-Golgi Marker (ab277236)

    Immunofluorescence analysis of HeLa (Human cervix adenocarcinoma epithelial cell) cells labelling GM130 with ab277236. The cells were fixed with 4% formaldehyde (10 min), permeabilized with 0.1% Tween for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab277236 at 1/2500 dilution (pseudocolored in red) and Alexa Fluor® 488 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker ab195887, Mouse monoclonal to alpha Tubulin (Alexa Fluor® 488), at 1/250 dilution (shown in green). Nuclear DNA was labelled with DAPI (shown in blue).

    Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

    This product also gave a positive signal under the same testing conditions in HeLa cells fixed with 100% methanol (5 min).
