TRPS1 [MD274R]

Trichorhinophalangeal syndrome I (TRPS1), a 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. Defects in TRPS1 are the cause of tricho-rhino-phalangeal syndrome type 1. TRPS1 binds to the NuRD complex via CHD4 and can repress other key transcription factors such as p63 and estrogen receptor. It is expressed at higher levels in androgen-dependent prostate cancers, reducing the expression of PSA.
