LDB1
LDB1 (LIM domain-binding protein 1) is a gene whose normal job is to hold cell growth in check. The public catalogues list it as a tumour suppressor, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Medulloblastoma and Paediatric low-grade glioma.
Overview
Binds to the LIM domain of a wide variety of LIM domain-containing transcription factors. May regulate the transcriptional activity of LIM-containing proteins by determining specific partner interactions. Plays a role in the development of interneurons and motor neurons in cooperation with LHX3 and ISL1.
IntOGen calls it a driver in 3 cohorts (0 activating, 3 loss-of-function), covering Medulloblastoma, Pilocytic Astrocytoma.

Binds to the LIM domain of a wide variety of LIM domain-containing transcription factors. May regulate the transcriptional activity of LIM-containing proteins by determining specific partner interactions.
- 3 · How drugs use it
No product in this corpus aims at LDB1 yet. Because the protein is lost rather than overactive, drugs either restore its function or exploit the weakness its loss leaves (synthetic lethality).

Biology
Binds to the LIM domain of a wide variety of LIM domain-containing transcription factors. May regulate the transcriptional activity of LIM-containing proteins by determining specific partner interactions. Plays a role in the development of interneurons and motor neurons in cooperation with LHX3 and ISL1. Acts synergistically with LHX1/LIM1 in axis formation and activation of gene expression. Acts with LMO2 in the regulation of red blood cell development, maintaining erythroid precursors in an immature state. Location: Nucleus (UniProt). Locus 10q24.32 (HGNC).

Notes
top- 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: IntOGen calls it a loss-of-function (LoF) driver in 3 cohorts. Evidence tier "cohort-driver" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
