The PITX1 gene provides instructions for making a protein that plays a critical role in development of the lower limbs. 3. Gene transcription is a complex process that involves the interactions of proteins and regulatory regions of DNA. However, the Pitx1 protein is actually important in building other body parts and is therefore expressed in multiple . Development. This investigation was modified from the HHMI Stickleback Modeling activity where students examine two different forms of the the stickleback fish. Many freshwater populations of stickleback fish lack the long spines that project from the pelvis of their marine relatives. Elife.
