PTPRK protein tyrosine phosphatase receptor type K

ENSG00000152894 · protein coding · Open Targets profile

Regulation of processes involving cell contact and adhesion such as growth control, tumor invasion, and metastasis. Negative regulator of EGFR signaling pathway. Forms complexes with beta-catenin and gamma-catenin/plakoglobin. Beta-catenin may be a substrate for the catalytic activity of PTPRK/PTP-kappa. .

In 15 of 15 cancers, the evidence for PTPRK comes mainly from mutations found in tumours

Each row is a cancer, strongest overall evidence first. The two dots show how strong the inherited (germline) and tumour-mutation (somatic) evidence is; the line between them is the gap.

Scores run from 0 (no evidence) to 1 (strongest). A missing dot at 0 means Open Targets holds no evidence of that kind. Source: Open Targets Platform, fetched live.

gnomAD loss of function constraint: o/e 0.42135000228881836 (upper bound 0.5105900168418884). Low values mean loss of function is poorly tolerated, a safety flag for inhibition.

Who runs trials of these drugs

No named investigators on registry trials of PTPRK's approved or late-stage drugs in the last three years.

No terminated, withdrawn or suspended trials of PTPRK's drugs are registered

All 0 drugs and clinical candidates as a table

Each drug, stage and indication links to its Open Targets record, where the trials and approvals behind it are listed. Salt forms (for example a mesylate) are listed as Open Targets records them, as separate entries.
