| Subcellular_localization | CPB-1 staining was predominantly cytoplasmic, as indicated by a uniform strong signal that is excluded from nuclei. This cytoplasmic staining was specific: It was not detectable in cpb-1(RNAi) L4 hermaphrodites. The same pattern was observed in males. In contrast, a faint nonspecific staining was detected in nuclei throughout the gonad. | |||
| Type | Antibody | Affinity-purified polyclonal antibodies against the nonconserved N-terminal 258 amino acids of the protein. Doubly stained extruded gonads of wild-type and cpb-1(RNAi) hermaphrodites with anti-CPB-1 antibodies and the monoclonal SP56 antibody, which recognizes cells undergoing spermatogenesis, beginning at least as early as the primary spermatocyte stage. | ||
| Pattern | CPB-1 protein was detected at high levels in the L4 germ line, in a region just distal to the region that stained by SP56. An identical distribution was observed in males. | |||

| Remark | CPB-1 protein was not detectable in adult germ lines that have switched to oogenesis. Thus, although cpb-1 mRNA is present in adult hermaphrodites, which are making only oocytes, the protein is not. | |||
