Pathway link TAX1BP1-ULK1

TAX1BP1 ULK1

TAX1BP1 recruits ULK1.

TAX1BP1 can bring ULK1 to the lysosome instead of TBK1.

The same adaptor, TAX1BP1, can bring ULK1 instead of TBK1 to stressed lysosomes; either kinase then phosphorylates FNIP1.

The conditions it holds under

One study in human cell lines (ESP2026). Which kinase dominates in which cell type is not stated in the abstract. Full text not accessible when this link was written.

Studies behind it

YearEvidenceStudy
2026 M A TBK1/ULK1 signalling axis couples lysosomal stress to TFEB activation.ESP2026 Identifies a nutrient-independent lysosomal pathway in which v-ATPase recruits TBK1/ULK1 to phosphorylate FNIP1, inhibiting the FLCN:FNIP complex and releasing TFEB for nuclear translocation; recurrent ATP6V1B2 mutations found in follicular lymphoma patients constitutively hyperactivate this axis, driving TFEB-dependent tumor proliferation.

Points the other way

No study in the Atlas contradicts this link. That means none in this curated set, not none in the literature.
