FGF-13 Protein, Human

FGF-13 Protein, a microtubule-binding protein, directly binds and stabilizes tubulin, influencing microtubule polymerization. It negatively regulates axonal and leading process branching, crucial for neuron polarization and migration in the cerebral cortex and hippocampus. Additionally, FGF-13 regulates voltage-gated sodium channel transport and function, potentially impacting MAPK signaling. Interactions with SCN8A, SCN1A, SCN5A, SCN2A, and SCN11A suggest a role in modulating sodium channel activity and MAPK8IP2 scaffolding. FGF-13 Protein, Human is the recombinant human-derived FGF-13 protein, expressed by E. coli , with tag free. The total length of FGF-13 Protein, Human is 245 a.a., with molecular weight of ~27.6 kDa.

FGF-13, a microtubule-binding protein, exerts direct interaction with tubulin, participating in both the polymerization and stabilization of microtubules. This engagement in microtubule dynamics suggests a role in the refinement of axons by negatively regulating branching of axonal and leading processes. Additionally, FGF-13 plays a crucial role in the polarization and migration of neurons within the cerebral cortex and hippocampus. It further regulates voltage-gated sodium channel transport and function, influencing the activity of specific sodium channel isoforms. Beyond its microtubule-related functions, FGF-13 is implicated in the development of axonal initial segment-targeting inhibitory GABAergic synapses facilitated by chandelier neurons. Through its diverse interactions, including those with various sodium channels and MAPK signaling components, FGF-13 emerges as a multifaceted player in the intricate regulatory network governing neuronal processes and synaptic functions.

Approximately 27.6 kDa

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of 20 mM Tris, pH 8.5, 500 mM NaCl.

<1 EU/μg; determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
