GOLM1 as a Radioligand Therapy Target
GOLM1, golgi membrane protein 1, is a cell-surface protein. In Human Protein Atlas immunohistochemistry, GOLM1 staining is highest in prostate cancer (100% of samples positive), breast cancer (100% of samples positive) and endometrial cancer (100% of samples positive). Clinical status: Discovery-stage (no clinical drug program).
Is GOLM1 a good radioligand therapy target?
Scored against the six criteria that decide whether a protein can become a radioligand therapy:
- ✅ Cell-surface accessibility: Localized to the cell surface, so a radioligand can reach it from circulation.
- ✅ Tumor expression: High IHC staining in prostate cancer, 100% of samples positive.
- ❔ Internalization: Not yet assessed.
- ⚠️ Clinical precedent: Discovery-stage (no clinical drug program)
- ❔ Shedding: Not yet assessed.
- ❔ Normal-tissue dosimetry: Check kidney, liver, bone marrow and salivary expression in the Human Protein Atlas tissue atlas.
GOLM1 expression in cancer
Protein expression of GOLM1 across 20 cancer types from Human Protein Atlas immunohistochemistry. The score is a weighted staining intensity from 0 to 1; "% positive" is the share of patient samples with detectable staining.

Is GOLM1 internalized?
Nuclens has not yet extracted internalization evidence for GOLM1. Internalization matters for radioligands because an internalizing receptor traps the radionuclide inside the tumor cell. Run a full analysis to pull the latest literature.
GOLM1 clinical trials
Discovery-stage (no clinical drug program). Nuclens hasn't indexed trials for GOLM1 yet. Search ClinicalTrials.gov for GOLM1 trials.
GOLM1 normal tissue expression
Normal-tissue expression in dose-limiting organs (kidney, liver, bone marrow, salivary glands) drives radioligand dosimetry risk. Nuclens is re-validating its normal-tissue values, so they are not shown here yet. See GOLM1 in the Human Protein Atlas tissue atlas, and read how normal-tissue expression predicts radioligand dosimetry risk.
GOLM1 gene essentiality (DepMap)
CRISPR knockout effect across 1258 cancer cell lines: -0.01 (not essential). Radioligands kill by radiation, not by blocking the target, so essentiality matters less than for inhibitors. A non-essential target can still be an excellent radioligand target.
