SH3 domain-binding glutamic acid-rich-like protein 3 is a protein that in humans is encoded by the SH3BGRL3 gene. [5]
The 10.5kDa protein SH3 binding glutamic acid-rich protein-like 3 has an isoelectric point of 5.0. SH3 binding glutamic acid-rich (SH3BGR) gene is located to human chromosome 21. Two homologous genes, SH3BGRL and SH3BGRL3 are located to chromosome Xq13.3 and 1p34.3-35, respectively and code for small proteins similar to the N-terminal region of the SH3BGR protein. [6] SH3BGRL3 protein shows a significant similarity to glutaredoxin 1 of E. coli , and all the three proteins are predicted to belong to thioredoxin-like protein family. Glutaredoxins (GRXs) are ubiquitous oxidoreductases, which catalyze the reduction of many intra-cellular protein disulfides and play an important role in many redox pathways. However, the SH3BGRL3 protein lacks the enzymatic function of glutaredoxins and may have a role as a regulator of redox activity. [7]
Proteins such as glutaredoxin and thioredoxin are reported as up-regulated in many cancers such as lung and pancreatic; they have been implicated in increased resistance of cancer cells to free-radicals. There is little current evidence which directly links SH3GRPL3 with survival in cancer cells, however the protein has recently been identified as up-regulated in glioblastoma multiforme compared to normal cerebral tissue on proteomic analysis. [8] Studies of acute promyelocytic leukemia cell line NB4 have also reported up-regulation of the protein. Conversely, the related protein SH3BGRL is reported to be downregulated in fibroblasts, lymphoid cells, and splenic tumor cells transformed by the viral oncogene v-Rel. [9] Co-expression of SH3BGRL with v-Rel in primary splenic lymphocytes reduced the number of colonies formed by 76%. Xu et al. reported SH3BGRPL3 protein as a post-translational modification of the 27kDa tumor necrosis factor alpha (TNF-α) inhibitory protein, TIP-B1. This protein is potentially involved in resistance of cells to the apoptosis-inducing effect of TNF-α. [10]
Tumor necrosis factor is an adipokine and a cytokine. TNF is a member of the TNF superfamily, which consists of various transmembrane proteins with a homologous TNF domain.
Thioredoxin is a class of small redox proteins known to be present in all organisms. It plays a role in many important biological processes, including redox signaling. In humans, thioredoxins are encoded by TXN and TXN2 genes. Loss-of-function mutation of either of the two human thioredoxin genes is lethal at the four-cell stage of the developing embryo. Although not entirely understood, thioredoxin is linked to medicine through their response to reactive oxygen species (ROS). In plants, thioredoxins regulate a spectrum of critical functions, ranging from photosynthesis to growth, flowering and the development and germination of seeds. Thioredoxins play a role in cell-to-cell communication.
In the field of cell biology, TNF-related apoptosis-inducing ligand (TRAIL), is a protein functioning as a ligand that induces the process of cell death called apoptosis.
Interleukin 32 (IL32) is proinflammatory cytokine that in humans is encoded by the IL32 gene. Interleukin 32 can be found in higher mammals but not in rodents. It is mainly expressed intracellularly and the protein has nine different isoforms, because the pre-mRNA can be alternatively spliced. The most active and studied isoform is IL-32γ. It was first reported in 2005, although the IL-32 gene was first described in 1992. It does not belong to any cytokine family because there is almost no homology with other cytokines.
Tumor necrosis factor ligand superfamily member 9 also known as 4-1BB ligand or 4-1BBL or CD137L is a protein that in humans is encoded by the TNFSF9 gene.
Fibroblast growth factor receptor 1 (FGFR1), also known as basic fibroblast growth factor receptor 1, fms-related tyrosine kinase-2 / Pfeiffer syndrome, and CD331, is a receptor tyrosine kinase whose ligands are specific members of the fibroblast growth factor family. FGFR1 has been shown to be associated with Pfeiffer syndrome, and clonal eosinophilias.
Matrilysin also known as matrix metalloproteinase-7 (MMP-7), pump-1 protease (PUMP-1), or uterine metalloproteinase is an enzyme in humans that is encoded by the MMP7 gene. The enzyme has also been known as matrin, putative metalloproteinase-1, matrix metalloproteinase pump 1, PUMP-1 proteinase, PUMP, metalloproteinase pump-1, putative metalloproteinase, MMP). Human MMP-7 has a molecular weight around 30 kDa.
Fibroblast growth factor receptor 4 is a protein that in humans is encoded by the FGFR4 gene. FGFR4 has also been designated as CD334.
Transcription factor E2F4 is a protein that in humans is encoded by the E2F4 gene.
Glutaredoxin-1 is a protein that in humans is encoded by the GLRX gene.
Forkhead box protein O4 is a protein that in humans is encoded by the FOXO4 gene.
Decoy receptor 3 (Dcr3), also known as tumor necrosis factor receptor superfamily member 6B (TNFRSF6B), TR6 and M68, is a soluble protein of the tumor necrosis factor receptor superfamily which inhibits Fas ligand-induced apoptosis.
Thioredoxin-interacting protein is a protein that in humans is encoded by the TXNIP gene.
Peroxiredoxin-5 (PRDX5), mitochondrial is a protein that in humans is encoded by the PRDX5 gene, located on chromosome 11.
B-cell maturation antigen, also known as tumor necrosis factor receptor superfamily member 17 (TNFRSF17), is a protein that in humans is encoded by the TNFRSF17 gene.
Glutaredoxin 2 (GLRX2) is an enzyme that in humans encoded by the GLRX2 gene. GLRX2, also known as GRX2, is a glutaredoxin family protein and a thiol-disulfide oxidoreductase that maintains cellular thiol homeostasis. This gene consists of four exons and three introns, spanned 10 kilobase pairs, and localized to chromosome 1q31.2–31.3.
SH3 domain-binding glutamic acid-rich-like protein is a protein that in humans is encoded by the SH3BGRL gene.
Zinc finger protein 366, also known as DC-SCRIPT, is a protein that in humans is encoded by the ZNF366 gene. The ZNF366 gene was first identified in a DNA comparison study between 85 kb of Fugu rubripes sequence containing 17 genes with its homologous loci in the human draft genome.
Tumor necrosis factor receptor 2 (TNFR2), also known as tumor necrosis factor receptor superfamily member 1B (TNFRSF1B) and CD120b, is one of two membrane receptors that binds tumor necrosis factor-alpha (TNFα). Like its counterpart, tumor necrosis factor receptor 1 (TNFR1), the extracellular region of TNFR2 consists of four cysteine-rich domains which allow for binding to TNFα. TNFR1 and TNFR2 possess different functions when bound to TNFα due to differences in their intracellular structures, such as TNFR2 lacking a death domain (DD).
