UniProtKB - Q2LMP1 (WNT3A_CHICK)
Protein
Protein Wnt-3a
Gene
WNT3A
Organism
Gallus gallus (Chicken)
Status
Functioni
Ligand for members of the frizzled family of seven transmembrane receptors (Probable). Functions in the canonical Wnt signaling pathway that results in activation of transcription factors of the TCF/LEF family (PubMed:17488271). Regulates chick apical ectodermal ridge formation (PubMed:17488271). Required for normal embryonic mesoderm development and formation of caudal somites. Required for normal morphogenesis of the developing neural tube (By similarity).By similarityCurated1 Publication
Caution
A palmitoylation site was proposed at Cys-77, but it was later shown that this cysteine is engaged in a disulfide bond.1 Publication

Post-translational modificationi
Palmitoleoylation is required for efficient binding to frizzled receptors (PubMed:22046319). Depalmitoleoylation leads to inhibit the Wnt signaling pathway (By similarity).By similarity1 Publication
Disulfide bonds have critical and distinct roles in secretion and activity. Loss of each conserved cysteine in WNT3A results in high molecular weight oxidized Wnt oligomers, which are formed through inter-Wnt disulfide bonding (By similarity).By similarity

Expressioni
Tissue specificityi
Expressed in cornea. Isoform 1 is expressed in the primitive streak, dorsal neural tube, proximal otic vesicle, the apical ectodermal ridge and the epithelium of feather buds.2 Publications
Developmental stagei
In the eye, the expression was observed at stage 23 in the ocular surface epithelium ventral to the corneal epithelium. Strongly expressed in the entire ocular surface at stage 26 including the corneal epithelium. Remained strongly expressed at stage 30.1 Publication
