WNT2B
Function
Ligand for members of the frizzled family of seven transmembrane receptors. Functions in the canonical Wnt/beta-catenin signaling pathway. Plays a redundant role in embryonic lung development.
Involvement in disease
Diarrhea 9
DIAR9
An autosomal recessive form of chronic diarrhea characterized by neonatal-onset of osmotic diarrhea that is not substrate specific, abnormal crypt and villus architecture, and significant fat malabsorption evidenced by high levels of fecal fat.
None
The disease is caused by variants affecting the gene represented in this entry.
Post-translational modifications
Palmitoleoylation is required for efficient binding to frizzled receptors. Depalmitoleoylation leads to Wnt signaling pathway inhibition.
Sequence Similarities
Belongs to the Wnt family.
Tissue Specificity
Isoform 1 is expressed in adult heart, brain, placenta, lung, prostate, testis, ovary, small intestine and colon. In the adult brain, it is mainly found in the caudate nucleus, subthalamic nucleus and thalamus. Also detected in fetal brain, lung and kidney. Isoform 2 is expressed in fetal brain, fetal lung, fetal kidney, caudate nucleus, testis and cancer cell lines.
