VEGF receptors are receptors for vascular endothelial growth factor (VEGF). There are three main subtypes of VEGFR, numbered 1, 2 and 3. Also, they may be membrane-bound (mbVEGFR) or soluble (sVEGFR), depending on alternative splicing.
This family represents the internal ribosome entry site (IRES) of the Picornaviruses. IRES elements allow cap and end-independent translation of mRNA in the host cell. The IRES achieves this by mediating the internal initiation of translation by recruiting a ribosomal 43S pre-initiation complex directly to the initiation codon and eliminates the requirement for the eukaryotic initiation factor eIF4F.
The FGF-1 internal ribosome entry site (IRES) is an RNA element present in the 5' UTR of the mRNA of fibroblast growth factor-1 and allows cap-independent translation. It is thought that FGF-1 internal ribosome entry site (IRES) activity is strictly controlled and highly tissue specific.
The FGF-2 internal ribosome entry site is an RNA element present in the 5' UTR of the mRNA of fibroblast growth factor-2. It has been found that the FGF-2 internal ribosome entry site (IRES) activity is strictly controlled and highly tissue specific. It is thought that translational IRES dependent activation of FGF-2 plays a vital role in embryogenesis and in the adult brain [1]. When expressed the fibroblast growth factor 2 FGF-2 protein plays a pivotal role in cell proliferation, differentiation and survival as well as being involved in wound-healing [1,2].
This family represents the internal ribosome entry site (IRES) of the hepatitis A virus. HAV IRES is a 450 nucleotide long sequence located in the 735 nt long 5’ UTR of Hepatitis A viral RNA genome. IRES elements allow cap and end-independent translation of mRNA in the host cell. The IRES achieves this by mediating the internal initiation of translation by recruiting a ribosomal 40S pre-initiation complex directly to the initiation codon and eliminates the requirement for eukaryotic initiation factor, eIF4F.
The Hepatitis C virus internal ribosome entry site, or HCV IRES, is an RNA structure within the 5'UTR of the HCV genome that mediates cap-independent translation initiation.
The insulin-like growth factor II (IGF-II) internal ribosome entry site IRES is found in the 5' UTR of IGF-II leader 2 mRNA. This RNA element allows cap-independent translation of the mRNA and it is thought that this family may facilitate a continuous IGF-II production in rapidly dividing cells during development. Ribosomal scanning on human insulin-like growth factor II (IGF-II) is hard to comprehend due to one open reading frame and the ability for the hormone to fold into a stable structure.
The L-myc internal ribosome entry site (IRES) is an RNA element present in the 5' UTR of the mRNA of L-myc that allows cap-independent translation. L-myc undergoes translation via the internal ribosome entry site and bypasses the typical eukaryotic cap-dependent translation pathway [1]. The myc family of genes when expressed are known to be involved in the control of cell growth, differentiation and apoptosis.
The N-myc internal ribosome entry site (IRES) is an RNA element found in the n-myc gene. The myc family of genes when expressed are known to be involved in the control of cell growth, differentiation and apoptosis. n-myc mRNA has an alternative method of translation via an internal ribosome entry site where ribosomes are recruited to the IRES located in the 5' UTR thus bypassing the typical eukaryotic cap-dependent translation pathway.
This family represents the internal ribosome entry site (IRES) of the pestiviruses. The pestivirus IRES allows cap and end-independent translation of mRNA in the host cell. The IRES achieves this by mediating the internal initiation of translation by recruiting a ribosomal 43S pre-initiation complex directly to the initiation codon and eliminates the requirement for the eukaryotic initiation factor, eIF4F. The classical swine fever virus UTR described appears to be longer at the 5' end than other pestivirus UTRs. This family represents the conserved core.
This family represents the Picornavirus internal ribosome entry site (IRES). IRES elements allow cap and end-independent translation of mRNA in the host cell. It has been found that La autoantigen (La) is required for Coxsackievirus B3 (CVB3) IRES-mediated translation, and it has been suggested that La may be required for the efficient translation of the viral RNA in the pancreas.
The HIF-1α internal ribosome entry site (IRES) is an RNA element present in the 5' UTR of the mRNA of HIF-1α that allows cap-independent translation. The HIF-1α internal ribosome entry site (IRES) allows translation to be maintained under hypoxic cell conditions that inhibit cap-dependent translation [1]. The hypoxia-inducible factor-1α protein (HIF-1α) is a subunit of the HIF-1 transcription factor, which induces transcription of several genes involved in the cellular response to hypoxia.
The Tobamovirus internal ribosome entry site (IRES) is an element that allows cap and end-independent translation of mRNA in the host cell. The IRES achieves this by mediating the internal initiation of translation by recruiting a ribosomal 43S pre-initiation complex directly to the initiation codon and eliminates the requirement for the eukaryotic initiation factor, eIF4F.
Vascular endothelial growth factor receptor 1 is a protein that in humans is encoded by the FLT1 gene.
C-fos-induced growth factor (FIGF) is a vascular endothelial growth factor that in humans is encoded by the FIGF gene.
Vascular endothelial growth factor B also known as VEGF-B is a protein that, in humans, is encoded by the VEGF-B gene. VEGF-B is a growth factor that belongs to the vascular endothelial growth factor family, of which VEGF-A is the best-known member.
Vascular endothelial growth factor A (VEGF-A) is a protein that in humans is encoded by the VEGFA gene.
Eukaryotic translation initiation factor 4 G (eIF4G) is a protein involved in eukaryotic translation initiation and is a component of the eIF4F cap-binding complex. Orthologs of eIF4G have been studied in multiple species, including humans, yeast, and wheat. However, eIF4G is exclusively found in domain Eukarya, and not in domains Bacteria or Archaea, which do not have capped mRNA. As such, eIF4G structure and function may vary between species, although the human eIF4G 1 has been the focus of extensive studies.
