Fibroblast growth factor 1 (FGF-1) also known as acidic fibroblast growth factor (aFGF), is a growth factor and signaling protein encoded by the FGF1 gene. [ 5 ] [ 6 ] It is synthesized as a 155 amino acid polypeptide, whose mature form is a non- glycosylated 17-18 kDa protein.
The mammalian fibroblast growth factor receptor family has 4 members, FGFR1, FGFR2, FGFR3, and FGFR4. The FGFRs consist of three extracellular immunoglobulin-type domains (D1-D3), a single-span trans-membrane domain and an intracellular split tyrosine kinase domain. FGFs interact with the D2 and D3 domains, with the D3 interactions primarily ...
The fibroblast growth factor receptors (FGFR) are, as their name implies, receptors that bind to members of the fibroblast growth factor (FGF) family of proteins. Some of these receptors are involved in pathological conditions. For example, a point mutation in FGFR3 can lead to achondroplasia.
Fibroblast growth factor receptor-like 1 is a protein that in humans is encoded by the FGFRL1 gene. [5] The protein encoded by this gene is a member of the fibroblast growth factor receptor (FGFR) family, where amino acid sequence is highly conserved between members and throughout evolution. FGFR family members differ from one another in their ...
The FGFR1 gene is located on human chromosome 8 at position p11.23 (i.e. 8p11.23), has 24 exons, and codes for a Precursor mRNA that is alternatively spliced at exons 8A or 8B thereby generating two mRNAs coding for two FGFR1 isoforms, FGFR1-IIIb (also termed FGFR1b) and FGFR1-IIIc (also termed FGFR1c), respectively. Although these two isoforms ...
Fibroblast growth factor receptor oncogene partner 2 (FGFR1OP2) was identified in a study on myeloproliferative syndrome (EMS). The study aimed to identify the partner genes to the fibroblast growth factor receptor 1 (FGFR1) involved in the syndrome. Using the 5'-RACE PCR technique, FGFR1OP2 was identified as a novel gene with no known function ...
A t(6;8)(q27;p11) chromosomal translocation, fusing this gene and the fibroblast growth factor receptor 1 gene, has been found in cases of myeloproliferative disorder. The resulting chimeric protein contains the N-terminal leucine-rich region of this encoded protein fused to the catalytic domain of FGFR1.
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.
