Protein Information
Name PRRX1
Synonyms PMX1
Function Acts as a transcriptional regulator of muscle creatine kinase (MCK) and so has a role in the establishment of diverse mesodermal muscle types. The protein binds to an A/T-rich element in the muscle creatine enhancer (By similarity).
Cellular Location Nucleus.

The paired related homeobox protein 1 (PRRX1) is a paired-type DNA-binding homeodomain that plays an important role as a key switch for neural cell lineage determination and is essential for development (1,2). PRRX1 is expressed in a number of undifferentiated mesenchymal cells in mouse embryos and adults (3). Mice with a disrupted PRRX1 gene show perinatal death with craniofacial and limb malformations (4). Low PRRX1 expression levels were significantly associated with metastasis and poor prognosis of breast and colorectal cancer (5).
