Intermine data mining platform for C. elegans and related nematodes

Expression Pattern :

Pattern  First detected during first cell division. It is more abundant in the posterior half of the embryo. Uniform distribution in oocyte and newly fertilized embryo. At the 2-cell stage, there is higher level of expression observed in the germline blastomere P1 than in somatic blastomere. Initially present at similar levels in both daughters of P1 but persists at high levels only in the germline daughter P2. Asymmetrical pattern is seen at each of the subsequent divisions of germline blastomeres. After division of the final germline blastomere P4, pos-1 is not detected in either daughters. In L4 larvae, staining observed in the immature gonads and in adults staining is detected in the mature gonad. Primary Identifier  Expr712
