Alkaline ceramidase 1 also known as ACER1 is a ceramidase enzyme which in humans is encoded by the ACER1 gene. [5]
ACER1 mediates cellular differentiation by controlling the generation of sphingosine (SPH) and sphingosine-1-phosphate (S1P). [5]
Ceramides are a family of waxy lipid molecules. A ceramide is composed of sphingosine and a fatty acid joined by an amide bond. Ceramides are found in high concentrations within the cell membrane of eukaryotic cells, since they are component lipids that make up sphingomyelin, one of the major lipids in the lipid bilayer. Contrary to previous assumptions that ceramides and other sphingolipids found in cell membrane were purely supporting structural elements, ceramide can participate in a variety of cellular signaling: examples include regulating differentiation, proliferation, and programmed cell death (PCD) of cells.
Histidine ammonia-lyase is an enzyme that in humans is encoded by the HAL gene. It converts histidine into ammonia and urocanic acid. Its systematic name is L-histidine ammonia-lyase (urocanate-forming).
Ceramidase is an enzyme which cleaves fatty acids from ceramide, producing sphingosine (SPH) which in turn is phosphorylated by a sphingosine kinase to form sphingosine-1-phosphate (S1P).
Protein-glutamine gamma-glutamyltransferase K is a transglutaminase enzyme that in humans is encoded by the TGM1 gene.
Inhibitor of nuclear factor kappa-B kinase subunit alpha (IKK-α) also known as IKK1 or conserved helix-loop-helix ubiquitous kinase (CHUK) is a protein kinase that in humans is encoded by the CHUK gene. IKK-α is part of the IκB kinase complex that plays an important role in regulating the NF-κB transcription factor. However, IKK-α has many additional cellular targets, and is thought to function independently of the NF-κB pathway to regulate epidermal differentiation.
Sphingosine-1-phosphate receptor 4 also known as S1PR4 is a human gene which encodes a G protein-coupled receptor which binds the lipid signaling molecule sphingosine 1-phosphate (S1P). Hence this receptor is also known as S1P4.
Protein-glutamine gamma-glutamyltransferase E is an enzyme that in humans is encoded by the TGM3 gene.
The ASAH1 gene encodes in humans the acid ceramidase enzyme.
Small proline-rich protein 3 is a protein that in humans is encoded by the SPRR3 gene, which is found within the epidermal differentiation complex (EDC).
Caspase 14 is an enzyme that in humans is encoded by the CASP14 gene.
Serine palmitoyltransferase, long chain base subunit 2, also known as SPTLC2, is a protein which in humans is encoded by the SPTLC2 gene. SPTLC2 belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family.
Neutral ceramidase is an enzyme that in humans is encoded by the ASAH2 gene.
Sphingomyelin phosphodiesterase 2 is an enzyme that in humans is encoded by the SMPD2 gene.
Sphingosine-1-phosphate phosphatase 1 is an enzyme that in humans is encoded by the SGPP1 gene.
Phosphatidylinositol 4,5-bisphosphate 5-phosphatase A is an enzyme that in humans is encoded by the INPP5J gene.
Glyoxalase domain-containing protein 4 is an enzyme that in humans is encoded by the GLOD4 gene.
Neutral ceramidase C also known as N-acylsphingosine amidohydrolase 2C or non-lysosomal ceramidase C or ASAH2C is a ceramidase enzyme which in humans is encoded by the ASAH2C gene.
Alkaline ceramidase 2 also known as ACER2 is a ceramidase enzyme which in humans is encoded by the ACER2 gene.
Alkaline ceramidase 3 also known as ACER3 is a ceramidase enzyme which in humans is encoded by the ACER3 gene.
Delta(4)-desaturase, sphingolipid 2 is a protein that in humans is encoded by the DEGS2 gene.
