FZD3 Protein, Human (Cell-Free, His)

FZD3 is a Wnt receptor that primarily activates the β-catenin canonical pathway, involving disheveled protein, GSK-3 kinase inhibition, nuclear β-catenin accumulation, and Wnt target gene induction. FZD3 Protein, Human (Cell-Free, His) is the recombinant human-derived FZD3 protein, expressed by E. coli Cell-free , with N-10*His labeled tag. The total length of FZD3 Protein, Human (Cell-Free, His) is 644 a.a., with molecular weight of 75.3 kDa.

FZD3, serving as a receptor for Wnt proteins, primarily engages in the beta-catenin canonical signaling pathway, orchestrating the activation of disheveled proteins, inhibition of GSK-3 kinase, nuclear accumulation of beta-catenin, and induction of Wnt target genes. A secondary signaling pathway involving PKC and calcium fluxes, observed in certain family members, raises questions about its distinct nature and potential integration with the canonical pathway, given the crucial role of PKC in Wnt-mediated GSK-3 kinase inactivation. Interactions with G-proteins are integral to both pathways. Wnt5A activation stimulates PKC activity through a G-protein-dependent mechanism. FZD3 is implicated in transducing polarity information during tissue morphogenesis and differentiated tissues, playing a critical role in controlling early axon growth and guidance processes. It is essential for the development of major fiber tracts in the central nervous system and regulates axon growth in specific populations of cranial and spinal motor neurons. Additionally, FZD3 is involved in the migration of cranial neural crest cells and contributes to the transmission of sensory information. It collaborates with FZD6 in neural tube closure and participates in establishing planar cell polarity, particularly in orienting stereocilia bundles in auditory and vestibular sensory cells. Furthermore, FZD3 promotes neurogenesis by maintaining sympathetic neuroblasts within the cell cycle through a beta-catenin-dependent mechanism. Interactions with VANGL2 further underscore its multifaceted role in cellular processes.

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of PBS, 0.05% Brij-78, 6%Trehalose, pH 7.4.

<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 5-50% of glycerol (final concentration). Our default final concentration of glycerol is 50%. Customers could use it as reference.

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.
