TTYH2 (Tweety Family Member 2): TTYH2 is a gene that encodes a protein part of the Tweety family. This protein is known for its ion channel activity, mainly involving chloride ions. Proteins in the Tweety family are important for ion transport across cell membranes, contributing to cellular homeostasis, regulation of cell volume, and maintaining ion balance. Although the complete functions of TTYH2 are still being studied, it may play significant roles in cellular physiology.
