TTYH2 (Tweety Family Member 2): TTYH2 is a gene that encodes a protein belonging to the Tweety family. This protein is known to have ion channel activity, particularly involving chloride ions. Proteins in the Tweety family play important roles in ion transport across cell membranes, contributing to cellular homeostasis, regulation of cell volume, and maintenance of ion balance. While the full functions of TTYH2 are still under investigation, it may have significant roles in cellular physiology.
