Active Recombinant Human/Mouse FGF8 Protein

• Cat.No.: FGF8-92H
• Product Overview: Recombinant Human/Mouse FGF8 Protein without tag was expressed in E. coli.

Specification

• Description: Fibroblast growth factor 8 (FGF-8) is a critical mitogenic factor that is required for normal development of the eye, ear, brain, and limb. FGF-8 functions broadly to promote cell proliferation, differentiation, and migration. Overexpression of FGF-8 increases tumor growth and angiogenesis. Human and mouse FGF-8 proteins show 100% homology.

Q&As

How does FGF8 participate in embryonic development, particularly in the patterning of the midbrain and limb buds, and what molecular events coordinate its spatial and temporal expression?

FGF8 is essential for midbrain and limb bud patterning during embryonic development. Spatial and temporal expression is coordinated by signaling pathways and transcription factors that regulate FGF8 expression.

How do post-translational modifications, such as glycosylation, impact the function of FGF8, and what is the significance of these modifications in modulating ligand-receptor interactions?

Post-translational modifications, including glycosylation, can influence FGF8 function. Glycosylation may modulate ligand-receptor interactions, affecting the specificity and strength of FGF8 signaling.

What is the structural classification of FGF8, and how does its tertiary structure influence interactions with FGF receptors and heparin sulfate proteoglycans?

FGF8 is a member of the fibroblast growth factor family with a β-trefoil tertiary structure. This structure dictates its binding to FGF receptors and heparin sulfate proteoglycans, essential for signal transduction.

How does FGF8 participate in the crosstalk between different signaling pathways, such as Wnt and Shh, and what are the consequences for tissue morphogenesis and organogenesis?

FGF8 engages in crosstalk with pathways like Wnt and Shh during tissue morphogenesis. This interaction influences organogenesis by coordinating cellular processes and ensuring proper tissue patterning.

Can you discuss the interactions between FGF8 and the extracellular matrix, and how these interactions influence the stability and bioavailability of FGF8 ligands in the tissue microenvironment?

FGF8 interacts with the extracellular matrix, affecting ligand stability and bioavailability. This interaction modulates FGF8 diffusion and gradients in the tissue microenvironment.
