The unexpected role of Drosophila OCRL during cytokinesis
Bibliographic record
Abstract
Inositides are intrinsic components of cell membranes that regulate a wide variety of cellular functions. PtdIns(4,5)P(2,) one of the most abundant phosphoinositides, is restricted at the plasma membrane where it regulates numerous functions including cell division. We have recently established that the Drosophila inositol 5-phosphatase, dOCRL, is essential for cytokinesis, the last step of cell division (Ben El Kadhi et al. 2011).(8) We demonstrated that dOCRL is required for the dephosphorylation of PtdIns(4,5)P(2) at the surface of endosomes, resulting in the restriction of this phosphoinositide to the cell cortex during cytokinesis. dOCRL is the Drosophila ortholog of human OCRL1, a PtdIns(4,5)P(2) phosphatase mutated in the X-linked disorder oculocerebrorenal Lowe syndrome. Here, we discuss the relevance of our findings with reference to the role of human OCRL1 in non-pathological and pathological conditions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
