Enhances the incorporation of serine into phosphatidylserine and sphingolipids. May play a role in providing serine molecules for the formation of myelin glycosphingolipids in oligodendrocytes (By similarity).
We report here cloning and characterization of a novel human gene, termed C5orf12, which is a putative membrane protein belonging to the TMS_TDE family. The cDNA encodes 423 amino acid with a putative molecular weight of about 47 KDa. Secondary structure prediction showed that C5orf12 contained 10 putative transmembrane helices, which has high identity with other family members. We performed RT-PCR to examine its expression pattern. The result showed that C5orf12 was highly expressed in placenta, skeletal muscle, spleen, thymus, testis and peripheral leukocyte while expressed weakly in heart and liver. C5orf12 has high identity with the rat TPO1, so we speculate that C5orf12 may also have a role in the brain development.
The process in which myelin sheaths are formed and maintained around neurons. Oligodendrocytes in the brain and spinal cord and Schwann cells in the peripheral nervous system wrap axons with compact layers of their plasma membrane. Adjacent myelin segments are separated by a non-myelinated stretch of axon called a node of Ranvier.
The chemical reactions and pathways involving phosphatidylserines, any of a class of glycerophospholipids in which the phosphatidyl group is esterified to the hydroxyl group of L-serine. They are important constituents of cell membranes.
Any process that activates or increases the frequency, rate or extent of transferase activity, the catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from a donor compound to an acceptor.
Protein involved in the synthesis of lipids, a diverse class of compounds which are insoluble in water but soluble in organic solvents. They include fats, oils, triacylglycerols, fatty acids, glycolipids, phospholipids and steroids.
Protein involved in the biochemical reactions of lipids. Lipids are a diverse class of compounds which are insoluble in water but soluble in organic solvents. They include fats, oils, triacylglycerols, fatty acids, glycolipids, phospholipids and steroids.
Protein involved in the synthesis of phospholipids, the major lipid component of most cellular membranes. Phospholipids are usually composed of two fatty acid chains esterified to two of the carbons of glycerol phosphate, the phosphate being esterified to a hydroxyl group of another hydrophilic compound, such as choline, ethanolamine or serine.

A reference proteome is a set of protein sequences derived from a complete proteome which constitutes a defined standard for a particular user community. Reference proteomes are manually defined according to a number of criteria. They cover the proteomes of well- studied model organisms and other proteomes of interest for biomedical and biotechnological research. Reference proteomes have been selected to provide broad coverage of the tree of life, and constitute a representative cross-section of the taxonomic diversity to be found within UniProtKB.
