Frizzled-4/CD344 Protein, Human (HEK293, Fc)

The Frizzled-4/CD344 protein is a receptor for Wnt proteins and is associated with the classical β-catenin pathway, activating disheveled proteins, inhibiting GSK-3 kinase, and triggering Wnt target genes. In retinal vascularization, it acts as a receptor for Wnt proteins and Norrin (NDP), stimulating β-catenin accumulation and LEF/TCF-mediated transcription. Frizzled-4/CD344 Protein, Human (HEK293, Fc) is the recombinant human-derived Frizzled-4/CD344 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of Frizzled-4/CD344 Protein, Human (HEK293, Fc) is 180 a.a., with molecular weight of ~43.3 kDa.

Frizzled-4/CD344 Protein serves as a receptor for Wnt proteins, particularly associated with the canonical beta-catenin signaling pathway, involving the activation of disheveled proteins, inhibition of GSK-3 kinase, nuclear accumulation of beta-catenin, and subsequent activation of Wnt target genes. In the context of retinal vascularization, Frizzled-4 plays a pivotal role by acting as a receptor for both Wnt proteins and norrin (NDP), facilitating beta-catenin accumulation and stimulation of LEF/TCF-mediated transcriptional programs. Although a secondary signaling pathway, featuring PKC and calcium fluxes, has been observed in some family members, its integration with the canonical pathway, particularly in the context of Wnt-mediated inactivation of GSK-3 kinase, remains uncertain. Frizzled-4's involvement in tissue morphogenesis and intercellular transmission of polarity information is suggested, with interactions observed with MAGI3, NDP, TSKU, and glypican GPC3, highlighting its intricate role in cellular processes and signaling cascades.
