A number of ELISA Kits are available that target Prickle Homolog 1, an alias of the protein, prickle planar cell polarity protein 1. The human protein, encoded by the gene PRICKLE1, is a member of the Prickle / espinas / testin family. The protein's cellular localization is indicated to be cytoplasmic and nuclear. Additional synonyms or past names for this protein may include: EPM1B, RILP. Homology is conserved in other species, such as Mouse, Rat, Frog.
