| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Has a role in transcriptional regulation. Acts in parallel with the Ras/MAPK and the PI3K/PKB pathways in the control of cell identity and cellular growth. Essential for regulation of the cytoskeleton and cell growth but not for cell proliferation or growth rate. Required specifically for the microtubule-based basal transport of lipid droplets. Plays a partially redundant function downstream of Raf in cell fate specification in the developing eye. Pair-rule protein that regulates embryonic cellularization, gastrulation and segmentation. Ref.1 Ref.2 Ref.7 Ref.8 Ref.9 |
| Subcellular location | |
| Developmental stage | |
| Disruption phenotype | Embryos lacking maternal lilli show specific defects in the establishment of a functional cytoskeleton during cellularization, and exhibit a pair-rule segmentation phenotype. Adults lacking lilli exhibit reduction in cell and organ size and partial suppression of the increased growth associated with loss of PTEN function. Ref.1 Ref.2 |
| Sequence similarities | Belongs to the AF4 family. Contains 1 A.T hook DNA-binding domain. |
| Sequence caution | The sequence AAL28786.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence ACX54921.1 differs from that shown. Reason: Frameshift at position 1210. |
