Prickle Homolog 2 (PRICKLE2)

By searching an EST database for sequences similar to those of Drosophila and Xenopus Prickle, Katoh and Katoh (2003) identified human PRICKLE2. The deduced 844-amino acid protein contains an N-terminal PET domain followed by 3 LIM domains and a C-terminal prickle homology domain. PRICKLE2 shares 51.9% overall identity with PRICKLE1 and 79.3% identity within the N-terminal PET and LIM domains. EST database analysis revealed that PRICKLE1 and PRICKLE2 are coexpressed in brain, eye, and testis; additionally, PRICKLE2 is expressed in fetal brain, adult cartilage, pancreatic islet, gastric cancer, and uterine tumor.Katoh and Katoh (2003) determined that the PRICKLE2 gene contains at least 8 exons and that the 5-prime untranslated region is interrupted by intron 1.
