| Pattern | Assay 1: A developmental Western blot using synchronized populations indicates that OMA-1 was expressed only in the adult with very little, if any, expression detectable in L1 through L4 larval stages. Assay 2: Extracts were prepared from three temperature-sensitive mutant strains that are defective in different aspects of germline development. At the permissive temperature (15 Centigrades) in all three strains, OMA-1 was expressed. At the nonpermissive temperature (25 Centigrades), glp-4(bn2) mutant worms do not produce a germline and do not express OMA-1. fem-3(e2006) mutant worms produce only oocytes and no sperm at 25 C and express OMA-1. Semidominant mutants fem-3(q20sd) at 25 C produce only sperm and no oocytes and do not express OMA-1. Thus, OMA-1 protein is expressed primarily in adult oocytes but not in sperm, consistent with the functional assay. | Primary Identifier | Expr1848 |
