Annotated Information
Gene Symbol
- Os12g0572800 <=> MEL2, OSMEL2
Function
- In other eukaryotes, RNA-recognition-motif (RRM) proteins are known to play essential roles in germ-cell development and meiosis progression. Rice MEL2 gene encodes MEL2 protein which shows partial similarity with human proline-rich RRM protein, deleted in Azoospermia-Associated Protein1 (DAZAP1), though MEL2 also possesses ankyrin repeats and a RING finger motif.
- MEL2 is required for regulating the premeiotic G1/S-phase transition of male and female germ cells and also establishing synchrony of male meiosis.
Mutation
- Expression analyses of several cell-cycle markers revealed that, in mel2 mutant anthers, most germ cells failed to enter premeiotic S-phase and meiosis, and a part escaped from the defect and underwent meiosis with a significant delay or continued mitotic cycles.
Sublocalization
- Immunofluorescent detection revealed that T7 peptide-tagged MEL2 localized at cytoplasmic perinuclear region of germ cells during premeiotic interphase in transgenic rice plants.
Evolution
