notes on protein function

ptk7 is a regulator of planar cell polarity.

at the cell membrane, ptk7 recruits dishevelled.

ptk7 effect and is required for cells ability to display contact inhibition

within migratory neural crest cells, the ptk7 protein is locaized at the cell membrane where cells contact each other

ptk7 interacts with canonical but non non-canonical Wnt ligands, which leaads to a cell membrane locaization of ptk7 ( in breast cancer cells lines, and wnt5a) (see Berger et al JCS 2017.)

summary from NCBI for human PTK7

This gene encodes a member of the receptor protein tyrosine kinase family of proteins that transduce extracellular signals across the cell membrane. The encoded protein lacks detectable catalytic tyrosine kinase activity, is involved in the Wnt signaling pathway and plays a role in multiple cellular processes including polarity and adhesion. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jul 2012]

gene expression

ptk7 is expressed in neural crest cells and is involved in /required for neural crest cell migration. (Podleschny et al PLOS one 2015)
