关于TNFRSF12A:
Tumor necrosis factor receptor superfamily member 12A(TNFRSF12A) is also known as Fibroblast growth factor-inducible immediate-early response protein 14, FN14, CD266 antigen and tweak-receptor. TNFRSF12A is a single-pass type I membrane protein, including a 27 aa signal peptide, a 53 aa extracellular domain, a 21 aa transmembrane domain and a 28 aa cytoplasmic domain. TNFRSF12A is highly expressed in heart, placenta and kidney. TNFRSF12A can be induced by FGF1 and phorbol ester. TNFRSF12A binds to TWEAK/TNFSF12A to initiate a signal transduction cascade, causing different cellular responses such as cell death, cell proliferation, and angiogenesis.
关于Glypican 5:
Glypican 5 is encoded by the gene GPC5, and belongs to the Glypican family. It is 572 AA at lenth, and has a natural variation on its 155 location at which ‘A’ can mutata into ‘V’. This protein mainly exist in cell membrane and is usually secreted to extracellular space to do its function such as bearing heparin sulfate. In adult, Glypican 5 is primarily expressed in the brain, and can also be detected in fetal brain, lung and liver.
关于Stratifin:
Stratifin (SFN) belongs to the 14-3-3 family of proteins that act as important regulators of intracelluar signal transduction through their ability to bind specific motifs phosphorylated on serine or threonine. There are at least seven isoforms that have been identified in mammals (beta, gamma, epsilon, sigma, zeta, tau and eta). SFN can detected in many tissues, highly expressed in stratified squamous keratinizing epithelium. SFN is indicated as an epithelial cell marker and serves as a tumor suppressor whose expression can be down regulated by methylation. In addition, SFN plays a key role in maintaining the G2 checkpoint in cells and preventing mitotic death.
