General annotation (Comments)

Function	Supports the intracellular PIP pool and to a lesser extent, the PI 4,5-P2 pool. It generates PIP from PI and, to a lesser extent, PI 4,5-P2 from PI 4-P. There are indications that it phosphorylates the D-5 rather than the D-4 position. Has a role at a late stage in endosome-related membrane trafficking, at a point when signal termination has occurred. Is not required for receptor silencing. Ref.5 UniProtKB Q9Z1T6
Catalytic activity	ATP + 1-phosphatidyl-1D-myo-inositol 4-phosphate = ADP + 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate. UniProtKB Q9Z1T6
Cofactor	Zinc By similarity.
Subcellular location	Endosome membrane. Note: Mainly associated with membranes of the late endocytic pathway. Ref.5
Disruption phenotype	Flies contain undetectable phosphatidylinositol 3,5-bisphosphate levels, show profound increases in cell and organ size, and die at the pupal stage. Mutant larvae contain highly enlarged multivesicular bodies and late endosomes that are inefficiently acidified. Even though endocytic receptor trafficking is impaired in fab1 mutants, Notch, Wingless, and Dpp signaling is unaffected. Ref.5
Sequence similarities	Contains 1 DEP domain. Contains 1 FYVE-type zinc finger. Contains 1 PI5K domain.
Sequence caution	The sequence CAA22949.1 differs from that shown. Reason: Erroneous gene model prediction.
