Overlay histogram showing HeLa cells stained with ab211349 (red line). The cells were fixed with 4% formaldehyde (10 min) and then permeabilized with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS / 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (ab211349, 1/500 dilution) for 30 min at 22°C.

Isotype control antibody (black line) was Rabbit IgG (monoclonal) Phycoerythrin (ab209478) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

Acquisition of >5,000 events were collected using a 50 mW Yellow/Green laser (561nm) and 586/15 bandpass filter.

This antibody gave a positive signal in HeLa cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Triton X-100 for 15 min used under the same conditions.

CTP synthase also known as CTPS or the CTP protein is an enzyme involved in pyrimidine metabolism. It catalyzes the conversion of UTP to CTP an essential step in nucleotide biosynthesis. The enzyme exists in two isoforms CTPS1 and CTPS2 with both found in various tissues but CTPS2 has a higher expression in the brain. CTP synthase has a molecular mass of roughly 70 kDa. CTPS can assemble into filamentous structures under certain conditions influencing its enzymatic activity. These filaments sometimes referred to as cytoophidia are observed in many types of cells.

Biological function summary

CTP synthase plays a significant role in the regulation of nucleotide pools. The enzyme ensures the balance of CTP levels necessary for DNA RNA and phospholipid synthesis acting as a rate-limiting step in these processes. CTPS is part of larger enzymatic complexes that aid in cellular response to nutrient availability and DNA damage. Allosteric regulation and product feedback inhibition modulate CTP synthase activity maintaining cellular homeostasis and a proper supply of CTP for various biosynthetic pathways.

Pathways

CTP synthase is an important component in the pyrimidine biosynthesis pathway essential for nucleic acid and lipid metabolism. The enzyme's activity is tightly linked to the salvage pathways collaborating with enzymes like ribonucleotide reductase to regulate deoxyribonucleotide levels for DNA replication and repair. These interactions highlight the enzyme's involvement in cellular proliferation and response to metabolic stresses underpinning its regulatory function in metabolic pathways.

CTP synthase activity disorders relate to cancer and neurodegeneration. Dysregulation of CTPS is associated with increased proliferation seen in certain cancers given its role in nucleotide biosynthesis. Research also indicates a link between CTPS activity and neurodegenerative diseases as nucleotide imbalance affects neural function. Additionally interactions with proteins involved in cell cycle control and apoptosis such as p53 and Rb further highlight CTPS's role in disease etiology influencing therapeutic strategies targeting these diverse conditions.

Target data

CTP synthase involved in the de novo synthesis of CTP, a precursor of DNA, RNA and phospholipids (PubMed : 16179339, PubMed : 17189248, PubMed : 17463002, PubMed : 24870241, PubMed : 28459447, PubMed : 34583994). Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as a source of nitrogen (PubMed : 16179339, PubMed : 24870241, PubMed : 28459447, PubMed : 34583994). CTPS1 CTP synthase activity plays a crucial role in the proliferation of activated lymphocytes and immunity; additional CTP being required to meet increased demand for DNA, RNA and lipid membrane biosynthesis in proliferating lymphocytes (PubMed : 24870241, PubMed : 8530356). In addition to CTP synthase activity, also acts as a protein deamidase that catalyzes the side chain deamidation of specific asparagine residues of proteins to aspartate (PubMed : 40240600). Acts as a negative regulator of innate immunity by mediating deamidation of 'Asn-85' of IRF3, preventing IRF3 from binding DNA (By similarity). Facilitates chromatin relaxation in response to DNA damage by mediating deamidation of 'Asn-76' and 'Asn-77' of histone H1, thereby promoting subsequent acetylation of histone H1 at 'Lys-75' (H1K75ac), increasing chromatin accessibility to facilitate the recruitment of DNA repair proteins (PubMed : 40240600).
