WormMine: RNAi WBRNAi00107819

• WormBase ID: WBRNAi00107819
• Phenotype Remark: Figure 2, ocrl-1 RNAi shows phagosome maturation defect; "Inactivation of OCRL-1, the inositol 5-phosphatase that hydrolyzes PtdIns(4,5)P2, caused prolonged MTM-1(C378S) duration on phagosomes like PPK-1 expression (see Fig 4, F and G)... Consistent with the sealing defect, ocrl-1(lf) phagosomes were not acidified, and the recruitment of maturation factors (RAB-5 and RAB-7) and lysosomes (NUC-1) was blocked (Fig 2, R-U' and X)... RNAi inactivation of the inositol 5-phosphatase OCRL-1 led to sustained MTM-1(C378S) duration on phagosomes (Fig 4 G)... the appearance of 2xFYVE on phagosomes was severely impaired, suggesting that sustained MTM-1 suppresses PtdIns3P accumulation (Fig 4, B, D, and G)... Overexpression of PPK-1 or inactivation of OCRL-1, which causes increased PtdIns(4,5)P2 on phagosomes, led to extended LST-4 duration accompanied by defective 2xFYVE appearance (Fig 2, V-X; Fig 6 C; and Fig S4, B-F)."

Identifier	Name	Description
WBPhenotype:0001846	phagosome maturation defective	Early phagosomes fail to undergo the maturation process following the ingestion of particulate material by phagocytosis; During maturation, phagosomes acquire markers of late endosomes and lysosomes.
