Storage	1. Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. 2. Avoid repeated freeze-thaw cycles. 3. Store working aliquots at 4°C for up to one week. 4. In general, protein in liquid form is stable for up to 6 months at -20°C/-80°C. Protein in lyophilized powder form is stable for up to 12 months at -20°C/-80°C.
Notes	Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Details

Target Function	Microtubule-binding protein which directly binds tubulin and is involved in both polymerization and stabilization of microtubules. Through its action on microtubules, may participate in the refinement of axons by negatively regulating axonal and leading processes branching. Plays a crucial role in neuron polarization and migration in the cerebral cortex and the hippocampus. May regulate voltage-gated sodium channels transport and function. May also play a role in MAPK signaling. Required for the development of axonal initial segment-targeting inhibitory GABAergic synapses made by chandelier neurons.
Subcellular Location	Cell projection, filopodium. Cell projection, growth cone. Cell projection, dendrite. Nucleus. Cytoplasm.; [Isoform 1]: Nucleus, nucleolus.; [Isoform 2]: Cytoplasm. Nucleus.
Protein Families	Heparin-binding growth factors family
Database References	HGNC: 3670 OMIM: 300070 KEGG: hsa:2258 STRING: 9606.ENSP00000359635 UniGene: PMID: 30257687 Autism-related protein MeCP2 regulates FGF13 expression and emotional behaviors PMID: 27916441 FGF13 was downregulated in human placentae with early-onset preeclampsia. FGF13 played an important role in maintaining placental trophoblast permeability via the modulation of E-cadherin. PMID: 29405966 We propose that, in cells in which activated oncogenes drive excessive protein synthesis, FGF13 may favor survival by maintaining translation rates at a level compatible with the protein quality-control capacity of the cell. Thus, FGF13 may serve as an enabler, allowing cancer cells to evade proteostasis stress triggered by oncogene activation. PMID: 27994142 Study screened the coding and splice site regions of the FGF13 gene in a sample of 45 unrelated probands where genetic epilepsy with febrile seizures plus segregated in an X-linked pattern; subsequently identified a de novo FGF13 missense variant in an additional patient with febrile seizures and facial edema. Results suggest that FGF13 is not a common cause of genetic epilepsy with febrile seizures plus. PMID: 27810516 identified two novel native phosphorylation sites in the C terminus of NaV1.5 that impair FGF13-dependent regulation of channel inactivation and may contribute to CaMKIIdeltac-dependent arrhythmogenic disorders in failing hearts. PMID: 28882890 These data showed the diversity of the roles of the FGF13 N-termini in NaV1.5 channel modulation and suggested the importance of isoform-specific regulation PMID: 27246624 the FGF13/Nav1.7 complex is essential for sustaining the transmission of noxious heat signals PMID: 28162808 for PCa patients after RP, FGF13 serves as a potential novel prognostic marker that improves prediction of BCR-free survival, in particular if combined with other clinical parameters. PMID: 26891277 The findings of this study reveal a novel cause of this syndrome and underscore the powerful role of FGF13 in control of neuronal excitability. PMID: 26063919 X-chromosome deletions may be a cause of WS with larger deletions being lethal to males and that FGF13 mutations may be a cause of Wildervanck Syndrome (WS).

The preferential expression of FHF2B in sensory neurons may provide a basis for physiological differences in sodium currents that have been reported at the nodes of Ranvier in sensory versus motor axons.

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
