What is the normal function of the PRICKLE1 gene?
The PRICKLE1 gene provides instructions for making a protein called prickle-like 1. The function of this protein is unclear, although it appears to play an important role in the development of the nervous system. Prickle-like 1 is likely part of a chemical signaling pathway known as noncanonical WNT signaling. During development before birth, noncanonical WNT signaling helps to determine the position of various components within cells (cell polarity). This pathway also regulates the movement of nerve cells (neurons) in the developing nervous system.
Studies suggest that prickle-like 1 interacts with other proteins, including RE1-silencing transcription factor (REST). The REST protein regulates several critical genes in neurons by turning off (suppressing) their activity. To regulate these genes, REST must enter the nucleus and attach (bind) to particular regions of DNA. Researchers believe that prickle-like 1 controls REST by transporting it out of the nucleus, which prevents it from binding to DNA and suppressing gene activity. It remains unclear how the interaction between prickle-like 1 and REST contributes to the normal development of the nervous system.
