## TL;DR

TRPS1 (Zinc finger transcription factor Trps1) is a protein that switches other genes on and off. In the public catalogues the evidence so far is association rather than a proven role. Tied to Breast cancer.

## Summary

Transcriptional repressor. Binds specifically to GATA sequences and represses expression of GATA-regulated genes at selected sites and stages in vertebrate development. Regulates chondrocyte proliferation and differentiation.

Open Targets scores its association with cancer at 0.58 (direct and indirect evidence; datatypes literature 0.99, affected pathway 0.25, animal model 0.57, genetic association 0.69).

## Fields

- Kind: Target
- Last checked: 2026-09-23
- Also known as: transcriptional repressor GATA binding 1; Zinc finger transcription factor Trps1; GC79
- Tags: cancer-genes-wave
- Symbol: TRPS1
- Class: transcription
- Biology: Transcriptional repressor. Binds specifically to GATA sequences and represses expression of GATA-regulated genes at selected sites and stages in vertebrate development. Regulates chondrocyte proliferation and differentiation. Executes multiple functions in proliferating chondrocytes, expanding the region of distal chondrocytes, activating proliferation in columnar cells and supporting the differentiation of columnar into hypertrophic chondrocytes. Location: Nucleus (UniProt). Locus 8q23.3 (HGNC).
- Where found: Breast cancer: Open Targets association 0.53 with breast cancer (MONDO_0007254)

## Notes

- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: none stated by the sources. Evidence tier "association-only" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
