Kinase Classification: Group PKL: Family GASK
The FJ kinases are a recently-emerging family of atypical PKL-fold kinases which function in the Golgi to phosphorylate secreted proteins and sugar residues on glycoproteins and are sometimes secreted. The founding member, Drosophila four-jointed phosphorylates a cadherin substrate on the extracellular domain and is implicated in planar cell polarity. FAM20B can phosphorylate xylose sugars within proteoglycans, and both FAM20A, FAM20B and FAM20C are associated with abnormalities in bone and tooth mineralization in humans and zebrafish. Some FK proteins may also be secreted from the cell.
Distinct subfamilies, FJ, FAM20A and FAM20B and FAM198 are found in bilaterian animals and some in lower animals, and unclassified homologs have also been found in Trypanosomes.
