Expression Pattern :

Pattern  The apical-basal polarity of the PAR protein persists through early gastrulation, although the level of PAR-2 diminishes. Later changes in PAR distribution were not analyzed further. Primary Identifier  Expr1820
Remark  Previous data: analysis of the PAR proteins has focused primarily on their anterior-posterior localization at the 1-cell stage and their roles in subsequent anterior-posterior polarity. After cell division begins, however, this anterior-posterior asymmetry is reiterated only in the lineage of cells that form the germline. In contrast, some somatic (non-germline) cells show an apical-basal polarity in PAR localization. Subcellular Localization  By the 4-cell stage, the posterior PAR protein PAR-2 is localized to basolateral surfaces, and is not detected on the apical surfaces of somatic cells.
