SESN3 (Sestrin 3): SESN3 is a member of the sestrin family of stress-responsive proteins. It plays a role in regulating cell growth and metabolism, particularly under conditions of cellular stress. SESN3 also contributes to antioxidant defence and has been linked to metabolic regulation, with potential implications for conditions such as obesity and diabetes.

SESN3

PTGER4 (Prostaglandin E Receptor 4): PTGER4 is a gene that encodes a receptor for prostaglandin E2 (PGE2), a lipid mediator involved in inflammation and immune responses. PTGER4 plays a key role in regulating immune cell activation, cytokine production, and other cellular functions, influencing the body’s inflammatory processes. It has been studied in the context of autoimmune and inflammatory diseases.

PTGER4

PTPRT (Protein Tyrosine Phosphatase, Receptor Type T): PTPRT is a gene that encodes a protein belonging to the protein tyrosine phosphatase family, which is important for cell signalling. It plays a role in regulating cellular processes such as cell growth and differentiation. Mutations in PTPRT have been linked to several cancers, particularly colorectal cancer, due to its involvement in signalling pathways that control cell proliferation.

PTPRT

MICAL2 (Molecule Interacting with CasL 2): MICAL2 is an enzyme belonging to the MICAL family, recognised for regulating cytoskeletal dynamics through the oxidation of actin. MICAL2 plays a key role in controlling the disassembly of actin filaments, which influences cell shape, migration, and intracellular transport. Its activity is essential for processes such as neurite outgrowth, axon guidance, and the maintenance of synaptic and vascular structures. By modulating the cytoskeleton, MICAL2 supports cell communication, differentiation, and movement. Dysregulation of MICAL2 has been linked to cancer progression, neurological disorders, and vascular diseases.

MICAL2

MRPS9 (Mitochondrial Ribosomal Protein S9): MRPS9 is a component of the mitochondrial ribosome, essential for the synthesis of proteins within mitochondria. It plays a vital role in producing proteins required for mitochondrial function and energy generation. Impairments in MRPS9 can reduce mitochondrial efficiency and may be associated with mitochondrial disorders, affecting overall cellular energy metabolism.

MRPS9

TP63 (Tumour Protein P63): TP63 is a member of the p53 family of transcription factors that plays a key role in the development and maintenance of epithelial tissues, as well as in cell cycle regulation and programmed cell death. It is involved in embryonic development, stem cell maintenance, and tumourigenesis. Mutations in TP63 can cause various developmental disorders and have been linked to certain cancers. Research continues to explore its dual roles in normal cell function and disease.

TP63

OXTR (Oxytocin Receptor): OXTR is a gene that encodes the receptor for oxytocin, a hormone involved in social bonding, sexual reproduction, childbirth, and maternal behaviours. It plays a key role in regulating social interactions and trust, and dysregulation may contribute to conditions such as autism and social anxiety disorders.

OXTR

NFE2 (Nuclear Factor, Erythroid 2): NFE2 is a transcription factor that regulates genes involved in erythropoiesis, the production of red blood cells. It plays a key role in the development and maturation of erythroid cells. Changes or mutations in NFE2 can affect red blood cell production and may contribute to blood disorders.

NFE2

RWDD3 (RWD Domain Containing 3): RWDD3 is a protein whose function is not yet fully understood. It is being studied for its potential roles in cellular processes and its significance to human health and disease.

RWDD3

SARDH (Sarcosine Dehydrogenase): SARDH is an enzyme involved in the metabolism of sarcosine, an intermediate in the conversion of choline to glycine. It plays a crucial role in one-carbon metabolism, which is essential for processes such as DNA methylation. Dysfunction of SARDH can affect metabolic pathways and has been associated with certain metabolic disorders.

SARDH

TMPRSS4 (Transmembrane Protease, Serine 4): TMPRSS4 is a member of the transmembrane serine protease family, located on the cell surface and involved in activating proteins by cleaving peptide bonds. TMPRSS4 plays important roles in physiological and pathological processes, including cell migration, invasion, and the regulation of epithelial-mesenchymal transition (EMT), which is critical for development, wound healing, and cancer metastasis. Its overexpression has been linked to the progression of various cancers, making TMPRSS4 a potential biomarker for cancer diagnosis and prognosis.

TMPRSS4

MPO (Myeloperoxidase): MPO is an enzyme predominantly found in neutrophils and plays a vital role in the body’s defence system. It produces hypochlorous acid and other reactive molecules from hydrogen peroxide to fight bacteria and pathogens. Although crucial for immune defence, MPO activity can also lead to tissue damage during inflammation and has been associated with diseases, including cardiovascular conditions, due to its involvement in oxidative stress.

PVR (Poliovirus Receptor): PVR is a transmembrane glycoprotein that acts as a receptor for poliovirus and related enteroviruses, enabling viral entry and infection. Beyond its role in viral recognition, PVR is crucial for cell-to-cell adhesion, immune regulation, and tissue homeostasis. It supports the integrity of epithelial and endothelial barriers through its participation in adherens and tight junctions. Interactions between PVR and ligands such as TIGIT and DNAM-1 help regulate immune cell activation, affecting both innate and adaptive immune responses. Dysregulation of PVR expression or function can significantly impact immune function and tissue integrity.

CACNA1D (Calcium Voltage-Gated Channel Subunit Alpha1 D): CACNA1D is a gene that encodes a subunit of the L-type voltage-dependent calcium channel, which is essential for regulating calcium influx in various cell types, especially in muscle and nerve cells. Mutations in this gene have been linked to conditions such as autism spectrum disorders, epilepsy, and certain cardiac dysfunctions.
