Teashirt homolog 3 is a protein that in humans is encoded by the TSHZ3 gene.[1] In mice, it is a necessary part of the neural circuitry that controls breathing. The gene is also a homolog of the Drosophila melanogaster teashirt gene, which encodes a zinc finger transcription factor important for development of the trunk.

Tshz3-knockout mice do not develop the respiratory rhythm generator (RRG) neural circuit, which is a pacemaker that produces an oscillating rhythm in the brainstem and controls autonomous breathing. The RRG neurons are present, but are abnormal. Those mice do not survive because they don't initiate breathing after birth. Tshz-3 is being studied for its relationship to infant breathing defects in humans.[2]
