Phosphatase Classification: Fold CC1: Superfamily CC1: Family Paladin: Subfamily Paladin
Evolution
Paladins are found in vertebrates and early metazoa such as sponge, trichoplax and nematostella but absent from arthropoda and nematoda. Paladins are also found in most plants and a small number of fungi (see internal database gOrtholog).
Domain
The Paladin subfamily has a single domain, which lacks the cysteine residue at Cx5R catalytic motif common among CC1-fold phosphatases.
Function
Paladin has been very little studied. Human Paladin (PALD, PALD1) was found as an inhibitor of insulin signaling by knockdown and overexpression. Similar over and under-expression showed a role in neural crest cell formation and migration in chicken [1] and mutation of the two Cx5R cysteines did not affect this function.
