| Pattern | AIR-2 protein was specifically localized to meiotic chromosomes. Diffuse AIR-2 staining was found in the syncytial distal gonad and the cellularized oocytes of the proximal gonad. In the oocyte most proximal to the spermatheca, a striking localization of AIR-2 to meiotic chromosomes was found. Occasionally, faint AIR-2 staining of chromosomes was noticed in the neighboring oocyte as well. AIR-2 immunostaining of fixed gonads dissected from C. elegans males revealed that AIR-2 was also present on meiotic chromosomes in spermatocytes. AIR-2 staining was also found in mature sperm present in both males and hermaphrodites. However, in this case staining did not appear to be chromatin associated. Instead, AIR-2 appeared to be present in the cytoplasm and/or on the sperm membrane. | Primary Identifier | Expr1258 |
| Subcellular Localization | AntiAIR-2 staining of meiotic chromosomes persisted throughout both meiotic divisions and remained on the extruded polar body chromatin throughout embryogenesis. The staining of meiotic chromatin appeared to be localized to the interior face of the chromosomes. During both meiotic anaphases, AIR-2 staining was localized between the separating chromosomes. |
