ab203993 staining NuMA in HeLa cells. The cells were fixed with 4% formaldehyde (10 min), permeabilized with 0.1% Triton X-100 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 ab203993 at 1/5000 dilution (shown in green) and ab195889, Mouse monoclonal to alpha Tubulin (Alexa Fluor^® 594), at 1/250 dilution (shown in red). 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).

Supplementary information

NuMA also known as "nuclear mitotic apparatus protein" is a large protein with a mass of approximately 250 kDa. It localizes in the nucleus and becomes highly concentrated at the spindle poles during mitosis. NuMA proteins appear in a variety of cells especially in cells undergoing division. Researchers often refer to it by alternate names such as "anti NuMA" when discussing its interactions in cellular contexts. Scientists have developed products such as NuMA polyclonal antibodies to study this protein's function.

Biological function summary

The protein plays an important role in the organization of the mitotic spindle during cell division. It ensures that the spindle microtubules are correctly aligned and positioned. NuMA acts within a complex that includes dynein and dynactin facilitating proper chromosomal segregation. These actions are critical for maintaining genomic stability through accurate cell division.

Pathways

NuMA's involvement in the cell cycle is significant especially within the mitotic checkpoint control pathways. It interacts closely with proteins like pericentrin and LGN ensuring the efficient completion of mitosis. These interactions confirm the protein's importance in pathway regulation particularly during transition phases within the cell cycle.

Abnormal NuMA function has associations with cancer and certain genetic disorders like microcephaly. Changes in NuMA expression or malfunction can disrupt normal spindle formation leading to chromosomal instability a common hallmark of cancer cells. Its interaction with proteins like p53 further connects it to oncogenic processes suggesting that understanding NuMA's pathways could contribute to therapeutic strategies.

Target data

Microtubule (MT)-binding protein that plays a role in the formation and maintenance of the spindle poles and the alignement and the segregation of chromosomes during mitotic cell division (PubMed : 17172455, PubMed : 19255246, PubMed : 24996901, PubMed : 26195665, PubMed : 27462074, PubMed : 7769006). Functions to tether the minus ends of MTs at the spindle poles, which is critical for the establishment and maintenance of the spindle poles (PubMed : 11956313, PubMed : 12445386). Plays a role in the establishment of the mitotic spindle orientation during metaphase and elongation during anaphase in a dynein-dynactin-dependent manner (PubMed : 23870127, PubMed : 24109598, PubMed : 24996901, PubMed : 26765568). In metaphase, part of a ternary complex composed of GPSM2 and G(i) alpha proteins, that regulates the recruitment and anchorage of the dynein-dynactin complex in the mitotic cell cortex regions situated above the two spindle poles, and hence regulates the correct oritentation of the mitotic spindle (PubMed : 22327364, PubMed : 23027904, PubMed : 23921553). During anaphase, mediates the recruitment and accumulation of the dynein-dynactin complex at the cell membrane of the polar cortical region through direct association with phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2), and hence participates in the regulation of the spindle elongation and chromosome segregation (PubMed : 22327364, PubMed : 23921553, PubMed : 24371089, PubMed : 24996901). Binds also to other polyanionic phosphoinositides, such as phosphatidylinositol 3-phosphate (PIP), lysophosphatidic acid (LPA) and phosphatidylinositol triphosphate (PIP3), in vitro (PubMed : 24371089, PubMed : 24996901). Also required for proper orientation of the mitotic spindle during asymmetric cell divisions (PubMed : 21816348). Plays a role in mitotic MT aster assembly (PubMed : 11163243, PubMed : 11229403, PubMed : 12445386). Involved in anastral spindle assembly (PubMed : 25657325). Positively regulates TNKS protein localization to spindle poles in mitosis (PubMed : 16076287). Highly abundant component of the nuclear matrix where it may serve a non-mitotic structural role, occupies the majority of the nuclear volume (PubMed : 10075938). Required for epidermal differentiation and hair follicle morphogenesis (By similarity).
